Groups representing more than 2,000 legal educators have threatened to boycott the annual meeting of the Association of American Law Schools if the association moves ahead with plans to hold the event at a hotel owned by an opponent of same-sex marriage, The National Law Journal reported today.

The meeting is scheduled for January 6 to 10 at the San Diego Manchester Grand Hyatt. The hotel’s owner, Douglas F. Manchester, donated $125,000 earlier this year to an effort to amend the California Constitution to ban same-sex marriages.

The groups that have raised concerns are the Legal Writing Institute, and two of the law-school association’s sections, the Section on Legal Writing, Research, and Reasoning, and the Section on Teaching Methods.

“It’s a matter of principle,” said Louis Sirico, chairman of the Section on Legal Writing, Research and Reasoning. “We just don’t believe in this kind of discrimination.”

Another group, the Society of American Law Teachers, has also urged the law-school association to try to find an alternative location for the meeting.

Mr. Manchester, the hotel owner, did not respond to interview requests. Carl Monk, the association’s executive director, was unavailable for comment. —Katherine Mangan
