The College issued a new liquor policy yesterday banning all underage drinking and detailing the enforcement procedures for the new guidelines.

The new rules, which end a two week moratorium on drinking, are take effect today.

The policy, handed down after yesterday's meeting between the house masters and Dean of the College L. Fred Jewett '57, deals only with the procedures for the underage ban. No decision was made on last week's Undergraduate Council's proposals on methods of maintaining house spirit and unity.

The new policy includes six provisions. (See box at right).

Under the rules a student using a false form of I.D. could be disciplined.

The new policy applies to public parties sponsored by house committees, parties held in public areas, and masters' open houses. Private parties can continue to serve alcohol.

Trial Basis

However, the new policy is on a trial basis only, said Thomas A. Dingman '67, assistant dean of the College for the House System.

"The masters are going into this with the hope that this will work. If there is widespread non-compliance they have no alternative but to shut it down" and ban all alcohol on campus, Dingman said.

"We are depending on this thing working, and if it doesn't we'll have to review it," said Jewett. "We are not doing this as a fake cover."

Jewett said there would be an informal watch on the success of the underage ban.

New College Drinking Regulations
