Kenneth Countess, William Oscar McCoy, Luther Robinson, Leroy Gault, John Franklin Fairbanks and Donald Lee Harris were found guilty of committing divers crimes proscribed by the General Assembly of Maryland and against the peace, government and dignity of the State. They were duly sentenced.1 Upon appeal to the Court of Special Appeals of Maryland, the judgments against Countess, McCoy, Robinson, Gault and Fairbanks were affirmed, and those against Harris were reversed. Countess v. State, 41 Md. App. 649, 398 A.2d 806 (1979); McCoy v. State, 41 Md. App. 667, 398 A.2d 1244 (1979); Fairbanks v. State, 42 Md. App. 15, 398 A.2d 814 (1979); Harris v. State, 42 Md. App. 248, 400 A.2d 6 (1979). We granted certiorari in each of the cases. The petitioners present a common question concerning Maryland Rule 735, which concerns the election by a defendant of a court or jury trial in a criminal cause. The petitioners ask: “Did the Court of Special Appeals err in its interpretation and application of Maryland Rule 735?” Countess, McCoy, Robinson, Gault and Fairbanks contend that the court so erred in affirming the judgments against them. The State claims that the court so erred in reversing the judgments against Harris.

The Declaration of Rights of the Constitution of Maryland bestows upon a defendant in a criminal prosecution by this State the right to be tried by an impartial jury of his peers. Md. Const., Declaration of Rights, Articles 5, 21 and 24.2 *449When Chapter 700 pertaining to Criminal Causes was completely rewritten effective 1 January 1962, this right was recognized in terms of the waiver of it. Rule 741 read:
An accused may waive a jury trial and elect to be tried by the court. If an accused elects to be tried by the court the State may not elect a jury trial. An election to be tried by the court must be made before any evidence in the trial on the merits is taken unless otherwise provided by local rule of court.3
The Sixth Amendment to the Constitution of the United States includes the guarantee of a jury trial in criminal cases.4 In 1968 the Supreme Court of the United States, following its selective incorporation of Bill of Rights provisions into the Fourteenth Amendment, announced its belief that “trial by jury in criminal cases is fundamental to the American scheme of justice,” and held, therefore, that the right was applicable to the states through the Fourteenth Amendment. Duncan v. Louisiana, 391 U.S. 145, 149, 88 S.Ct. 1444 (1968). An accused may waive the right, but whether there is a proper waiver should be clearly determined by the trial court, and the determination must appear upon the record. Courts indulge every reasonable presumption against waiver of fundamental constitutional rights and do not presume acquiescence in the loss of them. Johnson v. Zerbst, 304 U.S. 458, 464-465, 58 S.Ct. 1019 (1938). The classic definition of waiver was enunciated in Johnson — “an intentional relinquishment or abandonment of a known right or privilege.” Id. at 464. The controlling standard depends on the considered choice of the accused. “A *450choice made by counsel not participated in by the [accused] does not automatically bar relief.” Fay v. Noia, 372 U.S. 391, 439, 83 S.Ct. 822 (1963). There must be an intelligent and knowing waiver by the accused. In the final analysis, “[t]he determination of whether there has been an intelligent waiver [of a fundamental right] must depend, in each case, upon the particular facts and circumstances surrounding that case, including the background, experience, and conduct of the accused.” Johnson at 464. See Curtis v. State, 284 Md. 132, 141-148, 395 A.2d 464 (1978).

In State v. Zimmerman, 261 Md. 11, 273 A.2d 156, decided 8 February 1971, this Court observed that it is established that “an accused may elect a court trial, thereby waiving a jury trial” and indicated that the election and waiver must be “knowing.” Id. at 12.5 Several months later, on 28 June 1971, Rule 741 was amended effective 1 September 1971. The former rule had been silent as to the mechanics of the election, and the revised rule went no further with respect to the procedural aspects of the election to be tried by jury or by court than to prescribe that “[s]uch election shall be made by the accused in open court when first called upon to plead after he is represented by counsel of record or has waived counsel.” It spoke in terms of “election” rather than “waiver,” see Miller v. Warden, 16 Md. App. 614, 622, n. 7, 299 A.2d 862 (1973), and authorized the court “in its discretion and for good cause shown, at any time prior to the trial [to] permit the accused to change his election.”
This Court, by order dated 31 January 1977, effective 1 July 1977, approved and adopted another revision of the entire Chapter 700. Under this revision the matter of election of court or jury trial was contained in Rule 735. On 16 November 1978, Rule 735 was amended to “take effect and apply to all proceedings commenced on and after January 1, 1979, and insofar as practicable, to all proceedings then pending----” *451As we see nothing to indicate that the 1978 amendments affect the cases in the posture in which they are before us, in determining the cases we shall consider the rule as it now stands, so that hereinafter, unless otherwise indicated, citations to sections are to sections of Rule 735 as presently in effect.
As under Rule 741, the prosecution has no say as to the mode of trial; whether the accused is to be tried by court or jury is his prerogative. It is now spelled out, however, that he shall exercise this prerogative by an election in writing, filed with the clerk of the court in which the case is pending within the time prescribed by Rule 731 for filing a plea. §§ a and b. The writing shall be substantially in the form set out in § b, which indicates it is to be signed by the accused, witnessed by his counsel, if any, and bear the date of its execution. In the suggested writing, the accused expressly acknowledges that he knows of his right to be tried either by a jury of 12 persons or by the court, and that to be convicted, he must be found to be guilty beyond a reasonable doubt in a jury trial by all 12 jurors, and, in a court trial by the judge. He designates which mode of trial he elects and asserts that he made the election “knowingly and voluntarily and with full knowledge that [he] may not be permitted to change [it].”
Even though an accused may be in full compliance with §§ a and b, that is, he has made an election by a writing substantially in the form prescribed, which writing has been duly executed and filed, if he has elected a court trial further steps are required. Despite the acknowledgments set out in the writing, before the trial of the case may proceed on the merits, the court must determine, “after inquiry of the defendant on the record, that the defendant has made his election for a court trial with full knowledge of his right to a jury trial and that he has knowingly and voluntarily waived the right. If the court determines otherwise it shall give the defendant another election pursuant to this Rule.” § d.
If an election is not filed in writing as required by §§ a and b, the court on its own motion or upon motion of the prosecution, may require the defendant, with his counsel, if any, to appear before the court to make an election in open *452court. § c. If the defendant then elects a court trial, the provisions of § d come into play. If he fails or refuses to make an election, the court shall advise him on the record that “his failure or refusal will constitute a waiver of his right to a trial by jury----” § c. Then, “if the court determines that the defendant knowingly and voluntarily is waiving his right with full knowledge of it, the defendant will be deemed to have elected a trial by the court.” Id.
Section e deals with a change of election. “Subject to the provisions of section d, after an election for a court trial is made, the court may not permit the defendant to change his election except upon motion made prior to trial and for good cause shown.” § el. “[D]ue regard to the extent, if any, to which trial would be delayed” shall be given by the court in its determination whether to allow a change. Id. After an election of a jury trial has been made, either pursuant to Rule 735 or in the District Court, “the defendant may waive his right to a jury trial at any time up to 72 hours prior to the time of trial,” but “[t]he court may allow a change in the election of a jury trial at any time before trial upon motion and for good cause shown.” § e2.6
Ill
In Zimmerman we had “hastened] to add” that we regarded it to be “the preferable practice in accepting an election of trial by the court from an accused ... for the trial judge at that time to determine on the record whether this *453is a knowing election on the part of the accused of a court trial in lieu of a jury trial in much the same manner as that specified by the Court of Special Appeals for acceptance of a guilty plea.” 261 Md. at 25-26. We took “cognizance of the fact that in some parts of the State trial counsel regularly advise their clients as to their recommendations as to election, but leave to the accused the actual stating of that election.” But, we cautioned, “[e]ven in those instances the preferable practice —■ and the practice calculated to reduce litigation — is for the trial judge to then ascertain that the election is knowingly made.” Id. at 26, n. 3. Rule 735 made this “preferable practice” mandatory, and set out the required details of the procedural scheme for the election of the mode of trial. The question posed by the petitioners here does not address the constitutional rights to a trial by jury. It does not challenge the effectiveness in the constitutional sense of the waiver by each defendant of those rights. It goes only to the interpretation and application of Rule 735 by the Court of Special Appeals. In short, all that is before us is whether there was compliance with the prescriptions of Rule 735 in the election made with respect to each defendant.7
As each defendant ultimately elected a court trial, our consideration focuses on § d of Rule 735 which we set out verbatim:
If the defendant elects to be tried by the court, the trial of the case on its merits before the court may not proceed until the court determines, after inquiry of the defendant on the record, that the defendant has made his election for a court trial with full knowledge of his right to a jury trial and that he has knowingly and voluntarily waived the right. If the .court determines otherwise, it shall give the defendant smother election pursuant to this Rule.
There are three aspects to this procedure: (1) the election; (2) the inquiry; and (3) the knowledge necessary for an effective waiver of a trial by jury.
*454(1)
It is patent that the determination of a court trial must be made by the defendant; no one may make the determination for him. Section a declares flatly that “a defendant shall elect to be tried by a jury or by the court.” Section d is invoked “[i]f the defendant elects to be tried by the court" and speaks in terms of “his election for a court trial.” (Emphasis added.) The most direct way to show that the election is that of the defendant is for him to so declare on the record in open court, or to place in the record a written election duly executed by him pursuant to § b. This is the preferable procedure, but the election may be voiced by his counsel in open court in the presence of the defendant.
(2)
The inquiry upon which the court determines that the defendant has made his election for a court trial with full knowledge of his right to a jury trial and has knowingly and voluntarily waived the right, must be “of the defendant on the record.” It is clear that the inquiry required for the determination must be addressed to the defendant in open court and recorded. The inquiry need not be conducted by the judge; it may be made by defense counsel or even by the prosecutor, but the responses must come from the defendant himself. The Rule does not envision that counsel simply report to the court that he has inquired of the defendant and given him the information necessary for an effective election. In order to assess properly the validity of an election under Rule 735 the court must not only know what was told the defendant but be in a position to evaluate the responses of the defendant to the information imparted. The information given, the questions asked of the defendant and by the defendant and the answers and comments made must be on the record so as to be available for appellate review if the election is questioned.
*455(3)
The requirement of § d that the defendant must “knowingly and voluntarily” waive the right to a jury trial goes no further than the mandates for a waiver of that right under the constitutions. If the waiver is determined by the court to have been an intention^/ relinquishment or abandonment of a known rigid., it meets the test of Rule 735d. For the court to ascertain whether it was a “known right” which was waived, § d prescribes that the defendant have “full knowledge of Ms right to a jury trial.” The defendant-petitioners urge that “[t]he term ‘full knowledge’ certainly implies understanding of the most salient features of trial by jury, including', at a minimam, the composition of the jury, the jury selection process, and the unanimity requirement.” This goes far beyond what is necessary for a waiver of a jury trial to be constitutionally effective; the Supreme Court has certainly not enunciated such a test. We do not believe that Rule 731) calls for knowledge of all the matters which the defendant-petitioners suggest are essential to a valid election of a court trial. Such detailed information regarding a jury is not indicated. What the Rule contemplates is that the defendant have a basic understanding of the nature of a jury trial. We think that this understanding is generally satisfied when the defendant entitled to a jury trial knows that he has the right to be tried by a jury of 12 persons or by the court without a jury; that whether trial is by a jury or by the court, his guilt must be found to be beyond a reasonable doubt; that in a jury trial all 12 jurors must agree that he is so guilty but in a court trial the judge may so find. These are the matters which the defendant acknowledges he is aware of in the written form of election set out in § b of the Rule in designating his election of court trial or jury trial, and normally they should suffice. We saw no need to go further when wo adopted the Rule, and we see no need to add other matters now. Ordinarily if the court duly determines that the defendant understands those aspects of a jury trial, he has, under the Rule, “full knowledge of his right to a jury trial.”
*456IV
The facts relevant to these appeals are presented to us by agreement pursuant to Maryland Rule 828 g.
Countess
Countess, before trial, elected a jury trial by a writing which was in the form designated by § b, signed by him and witnessed by an assistant public defender. Thereafter the appearance of a private attorney was filed. When the case came on for trial on 8 May 1978, the transcript of the proceedings shows that when asked by the clerk how he pleaded, his counsel responded by stating: “The plea is not guilty to all Counts in both indictments, Your Honor.” The transcript then reads:
THE CLERK: How do you elect to be tried?
THE DEFENDANT: Judge.
THE COURT: Okay. You understand you have a right to a Jury Trial, Mr. Countess?
(Whereupon, the Defendant indicated affirmatively by nodding his head.)
THE COURT: You understand that, sir?
THE DEFENDANT: Yeah, I understand.
THE COURT: Has your lawyer fully explained that ' to you?
THE DEFENDANT: Yeah.
THE COURT: And you have elected to be tried by the Court instead of a Jury?
THE DEFENDANT: Yeah.
THE COURT: I didn’t hear you.
THE DEFENDANT: Yeah.
THE COURT: All right, yeah, okay.
The trial proceeded. Countess was convicted of assault with intent to murder and carrying concealed a deadly weapon and was sentenced in due course.
The Court of Special Appeals was convinced that “the *457mandatory requirements of Rule 735 [had] been satisfied.” Countess v. State, 41 Md. App. at 657. The court reasoned:
Both the appellant and his attorney signed the form which is part of the record, and it contains all of the information required by Section b. On the day of trial, the appellant indicated, in response to questioning, that he understood that he had a right to a jury trial and that his lawyer had fully explained his right to him. The signed form and the in-court responses to questioning, show that the appellant made his election of a court trial with full knowledge of his right to a jury trial and that he knowingly and voluntarily waived the right. [Id. at 657-658.]
In open court, on the record, Countess elected a court trial. Neither the court nor his trial counsel mentioned the prior written election for a jury trial, and the lawyer who had witnessed the execution of the form was not counsel at trial. The circumstances under which it had been signed were not adduced. Although the election of a jury trial designated by the written form had been changed on the day the case was called to a court trial, no attempt was made to ascertain what had prompted the change. There was an inquiry by the judge of the defendant on the record, but the inquiry elicited no more than the barest affirmations by Countess that he understood that he had a right to a jury trial and that his lawyer had “fully explained that to [him].” Even if it be deemed to be implicit in the court’s permitting the trial to proceed without a jury that it had determined that Countess made his election for a court trial “with full knowledge of his right to a jury trial” and that he had “knowingly and voluntarily waived the right,” we do not see in the record sufficient information for us to ascertain whether the court had properly made such a determination. There may be circumstances under which a written election in substantially the form designated by the Rule would be enough to show an effective election of a court trial within the contemplation of § d, but such circumstances are not apparent here. The judgment of the Court of Special Appeals as to Countess is *458reversed and the case is remanded to that court with direction to reverse the judgments of the Criminal Court of Baltimore and to remand to that court for a new trial.
McCoy, Robinson and Gault
McCoy, Robinson and Gault were jointly tried. None of them had filed a writing electing a mode of trial. McCoy was represented by Karl H. Goodman, Esq., Robinson by Charles Shuman, Esq., and Gault by Russell J. White, Esq. When the case was called for trial on 2 August 1978 each defendant acknowledged the representation and in answer to inquiry by the court stated that he was satisfied with the services rendered by his attorney in the defense of the case. The transcript reflects:
THE COURT: Now, you have a right to a trial by jury. What’s the choice there?
MR. WHITE: As to Mr. Gault, Your Honor, he is aware that he has a right to a jury and he understands what a jury is, 12 people selected to hear his case. In which case they must return a unanimous verdict of guilt, either guilty or not guilty. He elects to waive that right and be tried by the court.
THE COURT: Very well. Mr. McCoy?
MR. GOODMAN: Yes, sir. As far as Mr. McCoy’s concerned, court trial, Your Honor. Waiver of jury trial, the same as Mr. White just explained to his client.
THE COURT: Mr. Robinson?
MR. SHUMAN: Your Honor, Mr. Robinson’s waiving his right to a jury trial and will take a court trial. He has been fully advised that, of his Constitutional right to a trial by a jury comprised of 12 people. And knowing that right he is waiving his Constitutional right to a jury trial.
THE COURT: Very well then.
The court asked for the pleas. Each counsel pleaded his client *459not guilty and trial proceeded. Each defendant was found guilty of grand larceny and sentences were imposed.
The Court of Special Appeals affirmed the judgments. It said:
A review of the record in this case convinces us that the mandatory requirements of Rule 735 d have been met. As indicated above, counsel for each appellant announced the waiver of a jury trial and explained his client’s understanding of his right. At no time did the appellants, all of whom were present, voice any objection. Indeed, prior to the commencement of the State’s case, each appellant indicated that he was satisfied with the services of his attorney. Together, all of this shows that each appellant made his election of a court trial with full knowledge of his right to a jury trial and each knowingly and voluntarily waived the right. [McCoy v. State, 41 Md. App. at 674-675.]
There was no inquiry of any of the defendants on the record as required by § d. All the court had before it on which to determine whether each defendant made the election of a court trial with full knowledge of his right to a jury trial and knowingly and voluntarily waived the right came from the defendant’s counsel. As we have indicated, the responses to the inquiry must come from the defendant himself. Here counsel merely reported to the court that he had made inquiry of his client out of court and given the client the information necessary for an effective election. We have found that this is not sufficient under Rule 735. The judgments of the Court of Special Appeals as to McCoy, Robinson and Gault are reversed and the cases are remanded to that court with direction to reverse the judgments of the Circuit Court for Baltimore County and to remand to that court for new trials.
Fairbanks
Fairbanks did not file a written election of a jury or court trial. He was represented at the trial on 18 July 1978 by G. Warren Mix, Esq. When the case was called, Mr. Mix *460informed the court that he represented the defendant, that “we are familiar with each and every count of the indictment,” and that “[t]he plea will be not guilty to each and every count of said indictment.” Counsel continued:
Mr. Fairbanks understands what a jury trial is. He understands he has the absolute right to have a jury trial and wishes to waive that right and be tried by the Court here today. Is that correct. Mr. Fairbanks?
Fairbanks replied: “Yes, sir, it is.” As it appeared that the defendant had not been previously arraigned, the court made inquiry of defense counsel and Fairbanks concerning the criminal information. Upon assurance that the defendant understood the charges, trial proceeded. Fairbanks was convicted of robbery with a deadly weapon and with using a handgun in the commission of a felony. He was sentenced on 16 August 1978. The Court of Special Appeals affirmed the judgments. In finding that Fairbanks’ “waiver of a jury trial was properly accepted by the judge in accordance with Md. Rule 735,” it stated that § d
requires only that the court “determines, after inquiry ... on the record” that the election was knowing, voluntary, and with full knowledge of defendant’s rights. It does not require that the “inquiry” be by the court, only that it be on the record, to substantiate the court’s determination. [Fairbanks v. State, 42 Md. App. at 19.]
“That,” it asserted, “is precisely what was done here.” Id. It explained:
The attorney’s inquiry of [Fairbanks] and [Fairbanks’] subsequent affirmation, indicated a voluntary, knowing waiver of jury trial by [Fairbanks], with full knowledge of his right on the record. It was clearly sufficient to justify the court’s determination of a knowing and voluntary waiver. [Id.]
Although Fairbanks did indicate on the record that he *461understood what a jury trial was and that he understood he had the absolute right to a jury trial and wished to waive it, the record disclosed nothing further. The record is not sufficient to establish that he was aware that “before a finding of guilty in a jury trial all 12 jurors must find that [he was] guilty beyond a reasonable doubt,” but that in a court trial he could be convicted by the judge alone so finding. Thus, there was not a showing on the record that Fairbanks had the “full knowledge of his right to a jury trial” contemplated py § d. The judgment of the Court of Special Appeals is reversed and the case remanded to that court with direction to reverse the judgments of the Circuit Court for Baltimore County and to remand to that court for a new trial.
Harris
On 17 May 1978, the day after Harris was charged by a criminal information, he filed a written election of a court trial in substantially the form set out in § b. When the case was called for trial on 16 August 1978, the court referred to the offenses charged in each count and asked Patrick L. Rogan, Jr., Esq., defense counsel, if he had advised the defendant of his right to a jury trial. Defense counsel replied: “Yes, Your Honor. He pleads not guilty, Your Honor, and trial by the Court. The plea and election stand.” The court’s only comment was, “All right, sir.” The trial proceeded without further ado. Harris was convicted of robbery with a deadly weapon, two offenses of unlawful shooting and kidnapping, and duly sentenced.
In reversing the judgments and remanding the case for a new trial, the Court of Special Appeals stated that “there is nothing in the record of the in-court inquiry to show that [Harris] understood his right to a jury trial or that his waiver was voluntary.” Harris v. State, 42 Md. App. at 254. It observed:
The court’s inquiry was addressed to counsel and was limited to whether [Harris] had been advised of his right to trial by a jury.... [T]he court did not address [Harris] and [Harris] was given no opportunity to speak. There is no basis in this record *462for concluding that [Harris] acquiesced in any on the record explanation by counsel, ... or that he affirmed [a recital by his counsel]. [M]
The intermediate appellate court explained:
The purpose of section d is to require the trial judge to determine on the record that the election of a court trial is knowing and voluntary. Such a determination must be made regardless of whether the section b form has been filed and serves to ensure the voluntariness and intelligence of the written waiver. The rule requires that the inquiry be made “of the defendant.” In the present case no such inquiry was made and the appellant was not given the opportunity to state whether he understood his right to a jury trial or whether he was voluntarily electing a court trial. [Id.~\
It concluded, “therefore, that the record fails to show compliance with Rule 735 d and [Harris’s] conviction must be reversed.” Id. at 254-255. We agree. The judgment of the Court of Special Appeals is affirmed.
Manifest from all we have said is that the answer to the petitioners’ question is that the Court of Special Appeals erred in its interpretation and application of Rule 735 with respect to Countess, McCoy, Robinson, Gault and Fairbanks, but was correct in its interpretation and application of the Rule as to Harris.
V
The State suggests that failure to comply with Rule 735 does not compel reversal of a judgment of conviction and sentence. It believes that the interest of justice would be sufficiently satisfied under post conviction procedures whereby defendants “can attempt to establish that their waivers of a jury trial were less than voluntary or intelligent.” It opines that, in any event, there was simply a “technical failure to comply with Rule 735 d.” It points out that the Rule “does not create a new right” but “merely *463establishes a ritual for protecting the previously established right to a trial by jury.” It asserts baldly that the right to a jury trial “was fully honored at the trials below.” But that is precisely what cannot be determined because of the failure to comply with the dictates of the Rule. Its provisions are mandatory. On a number of occasions we have attempted to convey to bench and bar that our Rules “are not guides to the practice of law but precise rubrics ‘established to promote the orderly and efficient administration of justice and [that they] are to be read and followed.’ Brown v. Fraley, 222 Md. 480, 483 [, 161 A.2d 128] (1960).” State v. Bryan, 284 Md. 152, 155, 395 A.2d 475 (1978), quoting Isen v. Phoenix Assurance Co., 259 Md. 564, 570, 270 A.2d 476 (1970). In short, Rule 735 means what it says, and proceeding with the trials of the cases despite the failures to comply with its provisions requires reversal of the judgments of the trial courts and entitles the defendants to be newly tried.
In Appeal No. 86, judgments of the Court of Special Appeals reversed and cases remanded to that court with direction to reverse the judgments of the respective trial courts and to remand each case to the appropriate trial court for a new trial; pursuant to Maryland Rule 882 f, costs are not reallocated as part of the judgment of this Court.
In Appeal No. 49, judgment of the Court of Special Appeals affirmed; costs to be paid by Wicomico County.
. Countess was tried in the Criminal Court of Baltimore, McCoy, Robinson, Gault and Fairbanks were tried in the Circuit Court for Baltimore County, the first three of them jointly. Harris was tried in the Circuit Court for Wicomico County.
. “[T]he inhabitants of Maryland are entitled to ... the trial by Jury----” Md. Const., Declaration of Rights, Art. 5. “[I]n all criminal prosecutions, every man hath a right... to a speedy trial by an impartial jury____” Id., Art. 21. “[N]o man ought to be taken or imprisoned or disseized of his freehold, liberties or privileges, or outlawed, or exiled, or in any manner, destroyed, or deprived of his life, liberty or property, but by the judgment of his peers, or by the Law of the Land.” Id., Art. 24, formerly Art. 23.

There was also a right to a jury trial at the common law. Thompson v. State, 278 Md. 41, 49-52, 359 A.2d 203 (1976).
. For the purposes of the opinion in State v. Zimmerman, 261 Md. 11, 273 A.2d 156 (1971) the Court regarded the words “intelligently” and “knowingly” as “synonymous and interchangeable.” Id. at 13, n. 1.
. Prior to the 1978 amendment, § e read:
Where a defendant has a right to a jury trial and his cause has been transferred from the District Court because he has demanded a jury trial, he shall be tried by a jury and may not elect a court trial except with leave of court for good cause shown.
The General Assembly has provided by Acts 1978, ch. 963, effective 1 July 1978, see Code (1974, 1979 Cum. Supp.) § 8-305 of the Courts and Judicial Proceedings Article:
In any criminal proceeding the defendant may waive his right to trial by jury at any time up to 72 hours prior to the time of trial. Upon waiver of jury trial tne defendant shall be tried by the court sitting without a jury. The court may at any time before trial, upon motion and for good cause shown, allow a change in the election of a jury trial.
. Wejiote, however, that an election of a court trial which is valid under Rule _785 would meet the requirements of an effective waiver of the constitutional rights to a trial by jury.
