delivered the opinion of-the court:.
By leave of court an information in the name of the People of the State of Illinois, on the relation of M. D. Harvey, was filed in the circuit court of Lee county, requiring the appellants to show by what warrant .they exercised the offices of president and members of the board of education of a township high school district organized under section 6 of the act of 1911. The appellants filed a plea of justification, setting forth in detail the proceedings for the organization of the district, and the parties entered into a stipulation of facts forming an issue, which was submitted to the court. The stipulation was, “that said high school district was legally organized and said respondents were duly elected and have not been and are not usurping said offices, unless it be that said district is composed, in whole or in part, of another or prior township high school district.” // That question was to be determined from the following facts: On April 4, 1916, an election was held to vote for or against the proposition to establish a township high school for the benefit of township 20, range 10, in Lee county, under the general School law of 1909, and women were allowed to vote at the election. Counting only the votes of men the proposition was lost by six votes, but counting the votes of women there was a majority of 168 in favor of the proposition, and it was declared carried. On May 8, 1916, a petition was filed with the county superintendent of schools for an election for or against the proposition to establish a township high school under the act of 1911, comprising territory described in the information, including territory embraced in the first proceeding. Notice was given and an election was held on May 20, 1916, and the proposition was carried. On the same day there was an election for a board of education in the first township high school district and a board was elected, but the persons elected never organized nor exercised the duties of the office. On June 15, 1916, an election was held for a board of education under the second proceeding, at which the appellants were elected and organized as a board. The court did not decide the issue submitted by the stipulation but at the instance of the appellants held this proposition of law: “That the law under which the township high school was organized, to-wit, the act of 1911 of the School law of this State, is unconstitutional and void,” and entered a judgment of ouster, from which this appeal was taken.
The parties did not submit to the court the question of the validity of the act of 1911 but agreed that the high school district was legally organized unless it was composed, in whole or in part, of another and prior township high school district, but the judgment of the court was based on a finding that the act was unconstitutional. Parties cannot stipulate what the law is, but they may waive constitutional rights, and are generally held to have waived any question as to the validity of a statute by failing to make an attack upon it by opportune objection. Failure to make such objection is deemed a waiver. As has been frequently held, constitutional questions are waived by taking a case to an appellate court and assigning error there of which that court has jurisdiction. (Barnes v. Drainage Comrs. 221 Ill. 627; Case v. City of Sullivan, 222 id. 56; Pittsburg, Cincinnati, Chicago and St. Louis Railway Co. v. City of Chicago, 242 id. 178; 6 R. C. L. 94.) An estoppel may also be operative to prevent the assertion of a constitutional right, (10 R. C. L. 836,) so that a right may either be waived or lost. So far as the proposition of law held by the court was concerned, it was correct at the time the judgment was rendered, on March 24, 1917, (People v. Weis, 275 Ill. 581,) but by the act of June 14, 1917, the objection to the constitutionality of the act was removed. (People v. Stitt, 280 Ill. 553.) The question, however, was not submitted to the court and the constitutionality of the act was not involved in the issue.
The question to be determined under the stipulation was whether the first township high school district was legally organized, because if it was, the two could not occupy the same territory. Women voted at the election to organize that district, and the Woman’s Suffrage act of 1913 did not give them a right to vote at elections of that character. (People v. Peltier, 265 Ill. 630.) In 1915 an act was passed legalizing elections under the act of 1911 at which the votes of women were the deciding factor in carrying the election. (Laws of 1915 p. 630.) That act was held to be a valid exercise of legislative power in People v. Militzer, 272 Ill. 387, on the ground that the General Assembly had power,when the Township High School act was passed, to authorize women to vote at such elections, and it necessarily follows that the'act of 1915 gave women a right to vote at all elections for the organization of high school districts. The General Assembly could not at any time have passed an act authorizing women to vote at certain elections for the organization of high school districts but not at other elections for the same purpose, or under one act and not under another enacted for the same purpose, or limiting their right to vote at elections in which their votes were the deciding factor in carrying the election in favor of the proposition for organizing a district. It cannot be presumed that the General Assembly intended a violation of the constitutional provision that elections shall be free and equal by permitting women to vote at some elections to organize districts and not at others, making their votes legal provided they were cast to organize the district but illegal if they defeated the proposition, and the act of 1915 could only be sustained as conferring the right to vote at all elections to organize high school districts under any act. It was stipulated that the board of education elected on the same day as the election for the organization of the district in question had not organized or acted, and there was a question whether under the decision in People v. Niebruegge, 244 Ill. 82, the first township high school district, if legally organized, ceased to be a corporation by a non-user of its corporate powers. The proposition of law held, was not- upon the issue submitted and the judgment was not responsive to the issues, and the judgment must therefore be reversed. The stipulation of facts, if objected to, will' not be binding upon another trial. City of Alton v. Poster, 207 Ill. 150; Rigdon v. More, 242 id. 256.
The judgment is reversed and the cause remanded.
Reversed and remanded.
