The vote is the latest setback for Trinity Western University, a school with about 4,000 students in B.C.'s Fraser Valley, and is sure to amplify an ongoing debate over the rights of a private institution to impose its religious views about homosexuality on students.
The university, which plans to open a law school in the fall of 2016, requires students to sign a so-called community covenant. The document includes a passage that forbids sex outside of marriage, defined as between a man and a woman, and students can be disciplined for violating it.
The Federation of Law Societies of Canada and the Law Society of B.C.'s benchers have already voted to accept graduates of Trinity Western, which has also been accredited by the province's Advanced Education Ministry.
But more than a thousand B.C. lawyers signed a petition asking that the issue be put to the B.C. society's general membership, which happened at various locations throughout the province on Tuesday.
Lawyers voted 3,210 to 968 in favour of a motion calling on the society's benchers to reject the school.
The vote doesn't have any immediate effect, but the results will likely put considerable pressure on the law society's benchers to reconsider their earlier decision.
If the benchers don't substantially implement the results of the vote within a year, lawyers can submit another petition that could trigger a binding referendum.
University president Bob Kuhn described the results as "highly disturbing" and said the vote was driven by emotion rather than the law.
"It's effectively a rejection of freedom of religion in the context of equality rights," Kuhn said in an interview shortly after the results were announced.
"I think the decision is one of the majority and it's failing to protect the minority. ... It was simply: same-sex relationships trump religious freedom every time."
Trinity Western has also faced resistance elsewhere.
The Law Society of Upper Canada's board of directors voted not to accredit graduates from the school, while the council of Nova Scotia's law society voted not to accredit graduates unless the school either exempts law students from its covenant or removes the offending passage from the document.
The school has launched legal challenges of the decisions in Ontario and Nova Scotia.
If the B.C. law society's benchers implement Tuesday's vote, a similar challenge is almost certain to be filed in the province, though Kuhn said it was too early to speculate about whether that would happen. In addition, Toronto lawyer Clayton Ruby has filed a lawsuit in B.C. objecting to the provincial government's decision to accredit the school.
The issue could very well end up at the Supreme Court of Canada, which has previously ruled in the school's favour on the very same issue.
In 2001, the court overturned a decision by B.C.'s teachers' college to reject the school's teaching program.
The university's president said the high court's ruling remains the law, while opponents argued much has changed since the 2001 judgment, which occurred before a string of court cases that led to the legalization of same-sex marriage.
Lawyers who spoke against the school on Tuesday frequently invoked historic struggles for the rights of black people, women and other groups, while also noting that gay, lesbian, bisexual and transgender people still face discrimination today.
"I support religious freedom: you have every right to believe that I am a sinner," barbara findlay, a self-described "lesbian lawyer" who spells her name in lowercase letters, told her colleagues.
"But when your discriminatory beliefs turn into actions that discriminate against me, then that's where you've crossed the line."
Lawyer Vicente Asuncion said students who disagree with the university's community covenant can simply attend law school somewhere else.
"Law students have a choice to go to different universities, just like elementary and high school students have a choice go to public school or private school," Asuncion told the meeting.
"In effect, (a vote against the school) will be saying that all lawyers in B.C. must believe in same sex marriage."
