We perceive abroad today a mood to accept, unquestioningly, critical statements and charges against courts and their decisions which statements and charges, in charity, can be best described as irresponsible. For this reason, in light of the reported events which have transpired on various college campuses throughout this country and other countries throughout the world since the incident out of which the instant appeal arose, we deem it advisable to preface this opinion with a statement of what we do not decide herein.
We are not confronted here with the seizure or destruction of school property. We are not confronted here with the imprisonment of individuals on school property. We are not confronted here with the denial of access to the offices of a university. We are not confronted with the desecration of the flag, burning of draft cards, or assault on military personnel.
We are here concerned only with the propriety of the conviction of the individual defendants of the crime charged, under the circumstances hereinafter set forth.
On October 11 and 12,1965, the placement office of Michigan State University sponsored a “career car*57nival” in the student union building. Various public and private employers were invited to set up booths in the union and to visit with students who stopped at the booths. The purpose of the carnival was to acquaint students with employment opportunities with the employers represented. One of the participating employers was the United States Marine Corps. On the morning of October 12, the defendants entered the student union building with signs and literature which expressed opposition to the military activities of the United States in Vietnam. They positioned themselves in the general vicinity of the Marine Corps booth and proceeded to pass out their literature to the people who came by. At approximately 3 p.m. the director of the placement office approached the defendants and read to them the following statement:
“Pursuant to the authority vested by the Constitution, by the Legislature of the State of Michigan, by the Board of Trustees of Michigan State University, and by Administration of the University I am now advising you that you are occupying space assigned to others and that thereby you are trespassing upon University property, and you are further violating University ordinances by displaying signs and distributing handbills upon property governed by the Board of Trustees without authority and by obstructing free and normal use of University facilities. .
“You have ten minutes in which to move your materials and signs outside of this building. You are as welcome as any other student or guest to view the displays of this Career Carnival as long as your activities are lawful and orderly.”
The defendants declined to comply with the order and were arrested by university police officers.
A complaint was sworn out against the defendants charging them with unlawful conduct on 3 counts:
*581. Violation of Michigan’s trespass-after-warning statute. CL 1948, § 750.552 (Stat Ann 1954 Rev § 28.820 [1]).
2. Assembling in the student union building in a manner which obstructed the free and normal use of a university building and facility in violation of § 16.01 of the ordinances of Michigan State University.
3. Displaying a sign or poster on university property calling attention to conscientious objection and the Vietnam war, in violation of § 30.02 of the ordinances of Michigan State University.
Count 3 was dismissed because, according to one university official, the ordinance in question was designed to control commercial advertising. The defendants were tried on counts 1 and 2 in the justice court for Lansing township, were convicted on both counts, and were each sentenced to a fine of $35 plus costs, or 15 days in the county jail. They appealed to the Ingham county circuit court, sitting without a jury, and were again found guilty. The circuit judge sentenced defendants Halprin and Harrison to 30 days in the county jail and defendants Janvrin and Dukarm to 10 days in the county jail. All the defendants have appealed their convictions to this Court.
The convictions for trespass cannot stand. The claimed objectionable conduct of defendants was neither an unlawful entry into the building nor an unlawful presence there, but rather the activities in which they participated while in the union. The essence of our trespass-after-warning statute is that the owner or occupant of premises objects to the presence of certain individuals and orders them to depart, which order the individuals refuse to obey. The gist of the order given defendants in the case at bar was that they should remove their signs and materials from the building, but that they were welcome to be present and participate in the career *59carnival. Thus the objection was to the signs and material and not to the presence of the persons claimed to be trespassing. The impropriety of the charge under the statute is particularly clear in view of the cross-examination of defendant Janvrin by the prosecutor:
“Q. It was not a permanent eviction of you as an individual, was it?
“A. No.
“Q. You knew that you yourself was welcome there as a person?
“A. He had told me earlier in the morning that without my literature I was welcome as a guest of the University.”
The facts in this case are significantly different from those before the Court in People v. Weinberg (1967), 6 Mich App 345, where the defendants were “sit-ins” who were ordered to depart from private property and refused to do so. The trespass statute has no application in the instant case.
The terms of § 16.01 of the university ordinances, as they appear in the people’s brief, are:
“No person or persons shall, without authorization, assemble together anywhere on the campus for the purpose of creating any noise or disturbance, riot, ‘panty raid’ or other improper diversion, or assemble in a manner which obstructs the free movement of persons about the campus or the free and normal use of university buildings and facilities, or prevents or obstructs the normal operations of the university.”
The circumstances within which the defendants performed their complained of activities are of some significance in determining whether they have transgressed the university’s ordinance. The student union, where the events transpired, is a building ded*60icated to the use of students in pursuit of their own social, political, economic, and intellectual activities. The dean of students testified that there are no restrictions upon distribution of literature by students in the public areas of the union. There was a “career carnival” going on, and the public in general and students in particular were invited to come in and “browse.”' It is undisputed that defendants were not rowdy and were at all times polite and cooperative. The corroborated and uncontradicted testimony on behalf of defendants was to the effect that they were quick to move out of the way whenever requested to do so and that one of their group was commissioned to try to keep traffic flowing. Approximately 16,800 persons attended the carnival during its 2-day existence, and there was testimony that at times the carnival area became congested and it was sometimes difficult to approach some of the booths.
The question before us, then, is whether under the circumstances just related the conduct of the defendants was violative of the “obstruction” ordinance. Since this is a criminal prosecution the ordinance must be strictly construed and the convictions cannot be sustained unless the defendants’ conduct comes “clearly and unequivocally” within the spirit and letter of the ordinance. People v. Kirstein (1967), 6 Mich App 107, 114.
We hold it does not, for as we read the record, the nub of the charges against the defendants is that although they did not remain stationary, they were somewhat less mobile than other persons attending the carnival. This may indeed have aggravated the congestion that naturally resulted from the presence of such a large number of carnival patrons, but it is not enough, of itself, to constitute a violation of the ordinance and to bring into operation the penal consequences thereof. The “free and normal use of *61university buildings and facilities” in tbe context of this “career carnival” must surely encompass a significant degree of congestion in tbe carnival area. Tbe burden was upon tbe prosecutor to establish a violation of the ordinance. We bold that he failed to do so and, accordingly, the convictions must be set aside.
Reversed.
