Members of Harvard's graduate schools gathered in meetings yesterday to add their voices to the growing opposition in American universities to aggression in Southeast Asia and political repression at home.

More than 600 law students voted overwhelmingly yesterday to strike indefinitely to free students for anti-war activity in coming months.

The meeting approved three of the four resolutions passed at Monday's mass meeting, deleting only a phrase in a fourth resolution demanding freedom for Bobby Seale and the Black Panthers.

They called for the faculty "to show support for and participation in this strike" by cancelling classes and exams and granting course credit to students on a pass-only basis.

The Law faculty met for about two hours after the mass meeting and decided instead to allow students to miss their exams and make them up later. It refused, however, to cancel classes or exams, as the student gathering had requested.

Almost 100 law students attended a meeting last night to begin organizing for lobbying and community work in support of legislation introduced in the Senate today which would require with-drawal of all troops from Cambodia in 30 days and from Southeast Asia in eight months.

Thirty law students have registered their willingness to leave the Law School immediately to begin this work, which is being directed from Washington by a group headed by Sam Brown, a former Moratorium organizer.

At a later meeting conducted by members of the Law School Strike Committee, students made plans to establish a central office to coordinate all anti-war projects being conducted at the Law School. The students also voted to distribute leaflets today encouraging all students to strike despite the Law faculty's decision yesterday.

The group also called for a Law School rally at 1 p.m. today to protest that decision.

At a mass meeting yesterday afternoon, 1400 Business School students, faculty, and employees narrowly defeated a three-day strike proposal by a 700 to 685 vote. They decided instead to declare May 12 "a day of concentrated discussion and examination of the issues facing this country."

Other students, however, have saidthey intend to strike even though the motion was defeated. "A large proportion of the Business School is on strike. It's not business as usual," said Allen Minoff, chairman of the Strike Committee, in calling for picket lines this morning.

Several hundred first-year MBA students have withdrawn from the school's management simulation sessions. Many of them have said they will go to Washington tomorrow to speak to their Congressmen.

Yesterday's mass meeting called by a three-to-one margin for withdrawal of American troops from Southeast Asia and "an end to the use of blind force as a means to resolve legitimate disagreement' at home. They also acknowledged "that legitimate doubt exists about the ability of black Americans and other depressed groups to obtain justice."

A collection was taken after the meeting for an advertisement in the Wall Street Journal containing the ratified resolutions.

Six hundred members of the Ed School approved a strike yesterday afternoon, endorsing the resolutions of Monday's mass meeting. The meeting chose a student committee to prepare several, proposals concerning academic changes to be presented to a faculty meeting this morning.
