The struggle between Boston University students and administration seemed nearing a head last night as students reacted decisively to the president's decision to exercise effective control of the university's student-written weekly, the B.U. News.

Meeting in an emergency session last night, the B.U. Student Congress voted disapproval of Case's decision to invoke a dusty section of the newspaper's charter which permits the administration to censor student articles and compel the paper to print whatever articles the administration sees fit to submit.

In addition, the Congress demanded that the administration expunge this section frim the charter of the News before 5 p.m.

If Case rejects this ultimatum, the Congress says that it will allocate $300 for the publication of an alternate issue of the B.U. News.

Case, who is legally the publisher of the paper, and is technically entitled to control it, informed the editors that he intends to publish an editorial and a news story on the front page of this week's issue.

Case's demand apparently came in response to an article and an editorial in last week's issue decrying the administration's takeover of the F.M. radio station, WBUR, from student control.

Both the radio station and the newspaper have vociferously supported the recent student demands for a discount at the university-owned book store, which has been accused of "excessive profits."

Werner Bundschuh, editor-in-chief of the News, said that he had offered to print the president's articles 'in the appropriate columns," in a Saturday meeting with B. U. vice-president J. Wendell Yeo.

If Case does not accept the Student Congress proposal, Bundschuh said, he will not help prepare this week's edition of the News.

A spokesman for the newspaper said last night that Case had informed the News that he had no intention of arbitrating the matter or of discussing it. He said that the president had cancelled an appointment with Bundschuh.

Case refused to comment on the telephone last night.
