MISSOULA, Mont. -

University of Montana President Royce Engstrom has issued an order that everyone who attends next year's Foresters' Ball take a Breathalyzer test at the door.

The Associated Press reports Engstrom issued the order in a recent memo to forestry students in response to their ideas for eliminating binge drinking and debauchery at the 95-year-old party that takes place on campus.

Students call the Breathalyzer test offensive and intrusive.

Engstrom says he's willing to continue negotiating to find a workable solution.

At last year's event, students were thrown out or refused admission due to excessive intoxication, putting the future of the event at risk.

Students drafted a 30-page strategic plan that outlined new security and eliminated the "passion pit." Engstrom agreed to the changes but suggested several of his own.
