A new law school at Canada's Trinity Western University, in British Columbia, appeared to have won all necessary approvals last year to start -- despite criticism from human rights groups about the university's policy of barring students from having non-heterosexual sex. But a new round of opposition has emerged. Critics have gathered enough signatures on a petition to force a new vote by the Law Society of British Columbia, whose council had approved accreditation of the law school, The Globe and Mail reported. A vote by the larger membership could go the other way. And even if the law school holds on to its accreditation for British Columbia, its graduates will not be able to practice law in Ontario because that province's legal society voted Friday against recognition, CBC News reported. Nova Scotia's legal society has taken a similar position, although it also stated explicitly that if Trinity Western ends discrimination against gay people, its law school can be accredited so that its graduates could work in the province.
