On Second Motion for Rehearing.
CALVERT, Justice.Our opinion of July 21, 1954, on motion for rehearing and the concurring and dissenting opinions filed in connection therewith are all withdrawn and the following is filed as the opinion of the Court:
Since our opinion was released in this case, the Legislature has amended Section 4 of the Validating Act of 1953. See Senate Bill No. 10, Acts of the 53rd Legislature, 1st Called Session. As amended, the Section reads:
“Sec. 4. The provisions of this Act shall not apply to any city or town [now] involved in litigation at the time of the effective date of this Act (Chapter 177, Regular Session, Acts of the 53rd Legislature) questioning the legality of the incorporation or extension of boundaries [if such litigation is ultimately determined against the legality thereof].” Vernon’s Ann.Civ.St. art. 966c, § 4.
The words in italics were added by the amendment and the bracketed words were eliminated.
When the above language is considered in connection with the caption it is clear that the Legislature intended the amendment to have retroactive effect so as to apply to any city or town involved in litigation questioning the extension of its boundaries at the time of the effective date of the Validating Act of 1953. It is provided in the caption that Section 4, Chapter 177, of the Acts of the 53rd Legislature be amended so as to provide that such Act “shall not apply to any city or town involved in litigation questioning the legality of the incorporation or extension of boundaries, at the time of the effective date of the original Acf’. (Emphasis ours.) In the light of that provision of the caption it is significant that the amendment omitted the word “now,” and the purpose in inserting in parenthesis a citation to the original Validating Act of 1953 immediately following the reference to “this Act,” becomes clear. The citation clearly evidences that by the use of the words “this Act” it was intended to mean, not this amendment, but the original Validating Act which was being amended. The Legislature intended to accomplish something by the amendment, and if it be not given retroactive effect, it accomplished nothing. Petitioners point out that in the emergency clause it was pro*82vided that “this Act shall take effect and be in force from and after its passage,” and take the position that such language discloses a clear intent that the amendment be given only prospective effect. We attach no particular significance to that language. Its purpose was to make the amendment effective immediately as an emergency measure, thereby avoiding the usual 90-day period between the passage of an act and its effective date, as prescribed by Article III, § 39, of our Vernon’s Ann.St. Constitution.
The authority of the Legislature to enact this amendment and give it retroactive effect seems clear. Municipalities have no contract right in boundaries, and the Legislature has the same authority to enact legislation decreasing boundaries as it does to validate ordinances increasing boundaries. Lyford Independent School District v. Willamar Independent School District, Tex.Com.App., 34 S.W.2d 854; Dallas County Water Control and Improvement District No. 3 v. City of Dallas, 149 Tex. 362, 233 S.W.2d 291; McQuillin on Municipal Corporations, 3d Ed., Vol. 2, Sec. 4.05.
Our conclusion is that, since the City of Deer Park was involved in litigation questioning the validity of the extension of its boundaries at the time of the effective date of the Validating Act of 1953, it was excepted from the provisions of that Act by the amendment in question. This brings us to a consideration of the questions upon which the case was originally briefed before the Validating Acts were called to our attention.
The case reached us on application for writ of error containing three, and only three, points of error. The first and second points challenged holdings by the Court of Civil Appeals that the City of Deer Park had not been legally incorporated. Those points have been settled in favor of petitioner by the Validating Act of 1950 as is pointed out in our original opinion. We proceed, therefore, from the premise that at the time the annexation ordinance was passed Deer Park was vested with all the powers of a city of its class.
The third point contained in the application reads as follows: “The Court of Civil Appeals erred in holding Article 971, limiting superficial area upon original incorporation, also restricts the power of the subsequent annexation granted under Article 974.” The clear purport of this point and the argument under it is that whereas Article 971 limited the area of original incorporation to two square miles there was no such limitation of area that might be annexed under Article 974. The history of this litigation will demonstrate that if we should sustain this third point of error, even as we have sustained the first and second points, we would still be compelled to set aside our former judgment and now affirm the judgment of the Court of Civil Appeals.
By its ordinance No. 08 the City of Deer Park, purporting to act under authority given in Article 974, Vernon’s Annotated Texas Civil Statutes, undertook to annex approximately 1,050 acres of land, including 440 acres of land owned by respondents and lying north of the La Porte highway and by such highway detached from the remainder of the annexed territory. Article 974 reads as follows:
“When a majority of the inhabitants qualified to vote for members of the State legislature of any territory adjoining the limits of any city incorporated under, or accepting the provisions of, this title, to the extent of one-half mile in width, shall vote in favor of becoming a part of said city, any three of them may make affidavit to the fact to be filed before the mayor, who shall certify the same to the city council of said city. The said city council may, by ordinance, receive them as part of said city; * *
The quo warranto proceeding filed by respondents attacked the validity of the annexation ordinance on many grounds, one of which was that the 440 acres was detached from the remainder of the annexed territory and none of the three signers of the annexation petition was a resident of the detached area.
*83In his findings of fact the trial judge found that the 440 acres “by reason of its location and character of usé is detached from and does not constitute a part of the same territory as the property included in Ordinance No. 08 which is located south of the La Porte highway * * * ”; and, further, that “The persons who signed the petition for annexation are not inhabitants of that territory * * * which is located north of the La Porte highway and owned and occupied by the Relators.” The trial court’s sole conclusion of law was as follows :
“1. Ordinance No. 08 is invalid and void because the persons who executed the petition for annexation pursuant to which said Ordinance No. 08 was passed are not inhabitants of that territory included in said Ordinance No. 08 which is located north of the La Porte Highway and owned and occupied by the Relators, and said property owned and occupied by Relators located north of the La Porte Highway, by reason of its location and character of use is detached from and does not form and does not constitute a part of the same territory as the property included in said Ordinance No. 08 which is located south of the La Porte Highway, and therefore said attempted annexation was not made or done in compliance with the laws of the State of Texas.”
Pursuant to the findings of fact and on its conclusion of law the trial court granted the injunction prayed for.
In their brief in the Court of Civil Appeals petitioners had only two points of error. They were as follows:
“First Point
“The Court erred in its holding that the property owned and occupied by Relators located north of the La Porte Highway, by reason of its location and character of use is detached from and does not constitute a part of the same territory as the property included in said Ordinance which is located south of the La Porte Highway within the meaning of the term ‘territory’ as used in Article 974 of the Revised Civil Statutes of Texas (1925).
“Second Point
“The Court erred in holding the annexation Ordinance invalid and void because the persons who signed the petition for annexation pursuant to which Ordinance No. 08 was passed are not inhabitants of that territory located north of the La Porte Highway owned and occupied by Relators.”
In their reply brief the respondents had a counterpoint squarely joining issue on the foregoing points, and had three other counterpoints contending that the judgment of the trial court invalidating the annexation ordinance should be affirmed for the additional reasons that the City of Deer Park had not been legally incorporated, and that, if legally incorporated, it had no legal authority to extend its boundaries so as to include more than two square miles of territory. By way of reply petitioners controverted all of these matters. It was on this record and on the issues so joined that the case was submitted to the Court of Civil Appeals.
The opinion of the Court of Civil Appeals set out, in reasonable detail, the stipulated and undisputed material facts bearing on the detached character of the land north of the highway. 259 S.W.2d 284, 285-286, 287. In the interest of brevity those facts will not be repeated here. In its opinion the court then discussed the law bearing on the validity of the original incorporation of the city and its right and power to extend its boundaries so as to include a superficial area of more than two square miles, concluding in respect to these two issues that the city was not legally incorporated, and, even if it was, that it had no authority to so extend its boundaries. It concluded its discussion of these matters with a separate paragraph reading as follows: “In view of all the facts in this case we cannot say the court below erred in decreeing the ordinance in controversy to be invalid. There*84fore, we overrule both points of error in the original brief of appellants.”
Petitioners’ motion for rehearing in the Court of Civil Appeals contained thirteen assignments of error. Ten of the assignments were directed at holdings of the Court of Civil Appeals on the questions of validity of incorporation of the city and extension of its boundaries to include more than two square miles of territory. Assignment No. 8 asserted that “the Court of Civil Appeals erred in overruling Appellants’ First Point reading as follows: * * (here the First Point was quoted as it appeared in their brief).” Assignment No. 9 asserted that “the Court of Civil Appeals erred in overruling Appellants’ Second Point, reading as follows: * * * (here the Second Point was quoted as it appeared in their brief).” Assignment No. 13 asserted that “the Court of Civil Appeals erred in overruling Appellants’ Counterpoint Four, reading as follows: * * * (here their Counterpoint Four, also dealing with the ruling on the detached character of the acreage, was quoted as it appeared in their brief).” The motion for rehearing was overruled without written opinion.
It was with the record in this condition that petitioners presented to this court in their application for writ of error the three points of error heretofore described.
On original submission this court reversed the judgment of the courts below and rendered judgment for petitioners on the sole ground that by separate acts of the Legislature the proceedings for incorporation of Deer Park and the proceedings for extension of its boundaries had been validated. The Legislature then passed the Act quoted in the beginning of this opinion. Upon consideration of respondents’ first motion for rehearing we held that the Act was effective to except the Deer Park annexation proceedings from the operative effect of the Validating Act of 1953, just as we have done here and in the same language. We then proceeded to hold by a divided vote (5 to 3), in spite of respondents’ protestation that petitioners had assigned no error thereto, that both courts below had erred in holding the annexation proceedings void because of the segregated character of the territory north of the highway.
In their second motion for rehearing respondents insist that irrespective of the merits of the points of error contained in the application, petitioners’ right to a reversal is foreclosed by the ruling of the Court of Civil Appeals on the question of the detached character of the area to which ruling they assigned no error and by which they are therefore bound. On more mature consideration we are convinced this position is well taken.
Rule 476, Texas Rules of Civil Procedure, provides, in part: “Trials in the Supreme Court shall be only upon the questions of law raised by the assignments of error in the application for writ of error, * *
In Railroad Commission v. Mackhank Pet. Co., 144 Tex. 393, 190 S.W.2d 802, 803, this court, speaking through Chief Justice Hickman, said: “The Supreme Court is not clothed with supervisory powers over courts of civil appeals, but in cases which reach it by writ of error its review is limited to questions of law raised by assignments in the application.”
Where a court of civil appeals’ judgment may rest upon more than one ruling made by it the party aggrieved by the judgment must assign error to each such ruling or risk having the judgment affirmed on the ruling to which no error has been assigned. In such situations it is said that the petitioner has waived his right to complain of the ruling to which no error is assigned. Grayce Oil Co. v. Peterson, 128 Tex. 550, 98 S.W.2d 781, 786; London Terrace, Inc., v. McAlister, 142 Tex. 608, 180 S.W.2d 619, 622; 3A Tex.Jur., Appeal and Error, § 250. It follows that if the Court of Civil Appeals in this case ruled against petitioners on the “segregation” points before it, the judgment of the Court of Civil Appeals must be affirmed.
The wording of the paragraph heretofore quoted from the opinion leaves no doubt *85that it ruled against petitioner on these points. It said in words too plain to be misunderstood: “ * * * we overrule both points of error in the original brief of appellants.” Those were the two points of error, heretofore quoted, which dealt only with the conclusion of the trial court that the ordinance was invalid because it sought to annex 440 acres which, by its character and use, was detached from the territory south of the La Porte highway. The fact that the major portion of the opinion of the Court of Civil Appeals was devoted to a discussion of the law questions raised by respondents’ counterpoints did not make its ruling on the segregation points any the less emphatic or any the less final. The holding of the court was not that it sustained respondents’ counterpoints making unnecessary a decision of petitioners’ points, but that it overruled petitioners’ points. Moreover, this action was taken “in view of all the facts” in the case. But few of the facts in the case were pertinent to respondents’ counterpoints; almost all of them were pertinent to the detached character'and use of the particular 440 acres.
It can hardly be said that petitioners were misled by the opinion of the Court of Civil Appeals into believing that the segregation points had not been ruled on. Clear evidence to the contrary is the fact that three of the assignments of error in their motion for rehearing bore directly on these questions. Why these assignments were abandoned in the application for writ of error we cannot know and is immaterial. They were abandoned; and the right of petitioners to a reversal on the error, if any, involved in these rulings was waived. As said by the San Antonio Court of Civil Appeals in Kendall v. Johnson, 212 S.W.2d 232, 235: “It is the purpose of an assignment of error to point out, segregate and identify the particular ruling or action of the court which it is contended constitutes reversible error and the effect of the segregation and identification is to waive all other complaints as to all other rulings and actions of the court, unless they are also assigned as error.”
The policy of this court has been, and is, to give a liberal interpretation to points of error contained in an application for writ of error to the end that the rights of an aggrieved litigant will be protected against purely technical pitfalls and to discourage the filing of a great number of points of error where a few will suffice, but this policy cannot be carried to the extent of supplying a point of error on a controlling ruling of a court of civil appeals when the petitioner himself has accepted the ruling without complaint. We cannot regard matter contained in petitioners’ brief labeled “Petitioners’ Post-submission Argument” as though it were included in the application by way of amendment. Tardy amendment of an application does not accrue as a matter of right but only upon motion, with opportunity afforded to a respondent to oppose the amendment, and then only on such reasonable terms as the court may prescribe. Quite often the parties to a case pending in this court each file as many as five or six separate briefs and if we were to regard matters discussed in all briefs as amending an insufficient or defective application for writ of error so as to make it sufficient, we would enter a procedural morass from which we would soon be seeking extrication.
We do not regard the error, if any, in the ruling of the Court of Civil Appeals on the points dealing with the detached character and use of the 440 acres as fundamental error which this court may consider and declare in the absence of inclusion in the application of points of error seeking, review thereof. The error, if error it be, can hardly be classed, under the record before us, as the type of error “which directly and adversely affects the interest of the public generally” declared to be fundamental in Ramsey v. Dunlop, 146 Tex. 196, 205 S.W.2d 979, 983.
The position of respondents here is as simple as this: That no error having been assigned to the ruling of the Court of Civil Appeals on the segregation points, a ruling in itself sufficient to require an af-*86firmance of the judgment of the Court of Civil Appeals, the errors, if any, complained of in the three points of error were immaterial. This is the position they take in their second motion for rehearing. It is not the position they took in their reply to the application for writ of error. Their failure to take it at that point in the proceedings, however, can hardly be held to supply the petitioners with a point of error which they did not bring forward themselves.
Since our holding is that petitioners have waived their right to complain of the ruling of the Court of Civil Appeals on the points of error dealing with the invalidity of the ordinance because of the detached character and use of the 440 acres, it becomes not only unnecessary but improper to consider the correctness of that ruling.
This decision does not adjudicate that Deer Park is forever denied the right to annex the 440 acres. The judgment of the Court of Civil Appeals specifically preserved the right of the city to take further future action, and the injunction runs only against enforcement of the particular ordinance involved in this case.
Respondents’ second motion for rehearing is granted; our judgment of July 21, 1954, overruling respondents’ first motion for rehearing and our judgment rendered and entered herein on March 24, 1954, reversing the judgment of the courts below and dissolving the injunction, are set aside, and judgment is now rendered affirming the judgment of the Court of Civil Appeals.
All costs incurred in all courts through March 24, 1954 are assessed against respondents. Costs incurred in this Court since that date are assessed against petitioners.
