Opinion by
Mr. Chief Justice Bell,This case involves the challenged right of the President Judge of the Court of Common Pleas of Philadelphia to assign specially a Judge of the Trial Division of that Court to sit as a committing magistrate on the rearrest of a juvenile charged with murder and related crimes.
■ Louis Riggins, at the age of seventeen, was charged with murder and given a preliminary hearing on De*163oemher 17, 1968, before Judge Montemtjro of the then Juvenile Court Division of the Philadelphia County Court. Judge Montemtjro discharged Riggins, ruling that a prima facie case had not been made out; from this Order the Commonwealth appealed to this Court. This Court quashed the appeal as interlocutory: Riggins Case, 435 Pa. 321, 254 A. 2d 616.
Thereafter, Riggins was rearrested and was again charged with the same murder. A preliminary hearing was held before Judge Sloane, one of the Judges of the Philadelphia Court of Common Pleas, Trial Division. At this hearing, Riggins was held without bail for action by the grand jury. A pretrial petition for a writ of habeas corpus was filed in Riggins’s behalf, which raised the following questions: (1) was Judge Sloane’s Order a nullity because, as a Common Pleas Trial Division Judge, he had no authority, power or jurisdiction to sit as a committing magistrate to hear matters involving juveniles; and (2) was Riggins deprived of his Constitutional rights, especially the equal-protection and the due-process guarantees of the Fourteenth Amendment to the Constitution of the United States, since the assignment of Judge Sloane to sit as a committing magistrate was (a) at variance with the established custom and practice in Philadelphia and (b) beyond the power of the President Judge of the Court of Common Pleas.
Riggins’s petition for a writ of habeas corpus was denied by the lower Court, and from the Order denying his petition Riggins took this appeal. The Commonwealth has moved to quash the appeal on each and both of the following grounds. First, the Commonwealth contends that an Order denying a pretrial petition for a writ of habeas corpus is interlocutory and unappealable. Secondly, the Commonwealth contends that the question on appeal is now moot because more than a month before Riggins took his appeal to this *164Court, he was indicted by a grand jury for murder, aggravated assault and battery, assault and battery with intent to murder, carrying a concealed deadly weapon, unlawfully carrying a firearm without a license, and conspiracy. The Commonwealth further contends that the case is now moot because Riggins is no longer a juvenile and a decision in his favor in the present appeal would simply result in his rearrest and a hearing before a Judge of the Court of Common Pleas, Trial Division, and his subsequent reindictment by a grand jury.
In Commonwealth ex rel. Boatwright v. Hendrick, 436 Pa. 336, 260 A. 2d 763, we recently considered the right of appeal from the denial of a pretrial habeas corpus petition, and there laid down the following principles (pages 338-339) : “In cases involving criminal proceedings, an Order by a Judge of the Court of Common Pleas, denying, before indictment,* a writ of habeas corpus where the ground of appeal is the lack of adequate evidence to establish a prima facie case of crime by the accused, is interlocutory and unappealable and must be quashed: Commonwealth ex rel. Gordy v. Lyons, 434 Pa. 165, 252 A. 2d 197; Commonwealth ex rel. Bittner v. Price, 428 Pa. 5, 235 A. 2d 357; Commonwealth ex rel. Fisher v. Stitzel, 418 Pa. 356, 211 A. 2d 457; in the absence of exceptional circumstances (as, for example, cases involving great public interest or the safeguarding of basic human rights, Commonwealth v. Kilgallen, 379 Pa. 315, 108 A. 2d 780; Commonwealth v. Byrd, 421 Pa. 513, 219 A. 2d 293, cert. denied, 385 U.S. 886); or, unless expressly made so by statute, Commonwealth v. Pollick, 420 Pa. 61, 215 A. 2d 904; Commonwealth v. Wright, 383 Pa. 532, 119 A. 2d 492; or a challenge to appellant’s custody on grounds of lack of jurisdiction, Commonwealth ex rel. DiDio *165v. Baldi, 176 Pa. Superior Ct. 119, 106 A. 2d 910; Commonwealth ex rel. Nichols v. Hendrick, 197 Pa. Superior Ct. 646, 180 A. 2d 88.”
Riggins contends, inter alia, that his case involves both “'exceptional circumstances” and a challenge to his custody on the ground of lack of jurisdiction, and thus falls within the above-mentioned exceptions. In view of the fact that this case necessarily involves an interpretation of the Judiciary Article Y of the Constitution of Pennsylvania adopted in 1969, we believe this case involves great public interest and importance as well as a novel question of jurisdiction, and shall therefore decide it on the merits.
The new Constitution of Pennsylvania has consolidated all of the former separate Courts of Philadelphia County, such as the Court of Common Pleas, the Court of Oyer and Terminer and General Jail Delivery, Courts of Quarter Sessions of the Peace, Orphans’ Court and County Court (which had a domestic and a juvenile division), into a Philadelphia Court of Common Pleas with three Divisions—a Trial Division, and an Orphans’ Court Division, and a Family Court Division. Prior to this consolidation, the practice in Philadelphia was to bring juveniles charged with murder before a Judge of the juvenile division of the County Court for the purpose of conducting a preliminary hearing: Gaskins Case, 430 Pa. 298, 244 A. 2d 662. It is Riggins’s contention that since the adoption of the Constitution and the consolidation of the Philadelphia Courts, (1) a juvenile must be given a preliminary hearing only before a Judge who is a member of or regularly assigned to the Family Court Division, and, therefore, the President Judge of the new Court of Common Pleas had no right or power to specially order that Riggins’s preliminary hearing on rearrest be held before Judge Sloane, who is a member of and regularly assigned to the Trial Division of the Common Pleas *166Court; and (2) it is the function, right and power of the Administrative Judge of the Family Court Division to assign the case to one of the Judges in his Division. We disagree with Riggins’s interpretation.
Riggins appears to place his principal reliance on the following provisions of Section 16 of the Schedule to the Judiciary Article:
“The City of Philadelphia
“Section 16. Courts and Judges.—Until otherwise provided by law: (a) the court of common pleas shall consist of a trial division, orphans’ court division and family court division.
“(c) The judges of the county court shall become judges of the family court division of the court of common pleas and their tenure shall not otherwise be affected.
“(q) The court of common pleas through the family court division of the court of common pleas shall exercise jurisdiction in the following matters:
“(ii) Juvenile Matters: dependent, delinquent and neglected children and children under eighteen years of age, suffering from epilepsy, nervous or mental defects, incorrigible, runaway and disorderly minors eighteen to twenty years of age and preliminary hearings in criminal cases where the victim is a juvenile.*
A more persuasive argument could be made that Riggins’s preliminary hearing should have been con*167ducted before a Municipal Court Judge (formerly known as a magistrate) in light of Section (r) of the Schedule, which provides:
“(r) The municipal court shall have jurisdiction in the following matters: (i) Committing magistrates’ jurisdiction in all criminal matters. . . .”
The new Judiciary Article Y contains clauses or provisions some of which are ambiguous, and some overlapping or conflicting. It is important, and sometimes necessary, to carefully analyze and consider the individual provisions with the Article in its entirety.
Section (o) of the Schedule to the new Judiciary Article V provides, in pertinent part, that “the court of common pleas shall have all the jurisdiction now vested in the court of common pleas, the court of oyer and terminer and general jail delivery, courts of quarter sessions of the peace, orphans’ court, and county court.”
We first hold that the power of all Common Pleas Court Judges to sit as committing magistrates, which power existed prior to the adoption of the new Judiciary Article, continues to be retained by the Judges of the Court of Common Pleas.
With respect to the power of the President Judge to assign Judges, Sections 16(f) and 16(g) of the Schedule to the Judiciary Article pertinently provide: “(f) One of the judges of the court of common pleas shall be president judge and he shall be selected in the manner provided in section ten (d) of this article. He shall be the administrative head of the court and shall supervise the court’s judicial business.
“(g) Each division of the court of common pleas shall be presided over by an administrative judge, who shall be one of its judges and shall be elected for a term of five years by a majority vote of the judges of that division. He shall assist the president judge in supervising the judicial business of the court and shall *168be responsible to him. Subject to tbe foregoing, tbe judges of the court of common pleas shall prescribe rules defining the duties of the administrative judges. The president judge shall have the power to assign judges from each division to each other division of the court when required to expedite the business of the court.”
Even if it be assumed arguendo that Riggins should have his original preliminary hearing held before a Judge of the Family Court Division, Section 16(g), supra, specifically provides (we repeat) that “the president judge [of the Court of Common Pleas] shall have the power to assign judges from each division to each other division of the court when required to expedite the business of the court.” It is clear, therefore, that the President Judge has the Constitutionally granted power to assign any Judge from any Division of the Court of Common Pleas to any other Division of the Court to sit, consequently, as a committing magistrate. Judge Sloans had the jurisdiction, the right and the power to hear the Riggins case on his rearrest and to hold him for action by the grand jury.
Riggins further contends that the assignment by President Judge Carroll of Judge Sloans to sit as a committing magistrate in this case departed from the general practice in Philadelphia because the accused should be brought before the Judge of the Trial Division of the Court of Common Pleas who is assigned to hear miscellaneous criminal motions. He further states that at the time of the assignment of Judge Sloans, that Judge had already been specially assigned to supervise an investigating grand jury and the Judge who was assigned to the “miscellaneous criminal motion” list was available. Even assuming arguendo the fact of these allegations, there is no allegation that the alleged customary general practice involved a procedure *169or practice mandated by law, nor does Riggins indicate in what manner he was injured by this assignment.
We find no merit in any of Riggins’s contentions.
Order affirmed.
Mr. Justice Cohen and Mr. Justice Pomeroy would dismiss this case as moot, and therefore disagree with the Majority’s statement that “This case necessarily involves an interpretation of the Judiciary Article Y of the Constitution of Pennsylvania.”Italics throughout, ours, unless otherwise indicated.
We note parenthetically that Riggins does not contend that the victim in this case was a juvenile, nor does the record indicate that such was the case. Consequently, we see nothing in these provisions that mandates that a juvenile charged with a crime where the victim was not a juvenile must be given a preliminary hearing before a Judge of the Family Court Division.
