I dunno about the law school thing being linked to this it seems to me that the law school wanted to control their students sex lives, something completely unrelated to their ability or fitness to practise law
It had to do with freedom of religion. The school is private - unusual for universities in Canada - and religious, evangelical Christian. All students sign an agreement about adhering to various standards expected by their denominations, including that only heterosexual married students engage in sexual activity. The law school has only been opened fairly recently but the students of course are also evangelical Christians.
It wasn't students objecting to the agreement with the school, students can go to any number of other secular law schools,. The controversy was from was other lawyers who said that their credentials should not be recognised, because their right to attend a religious body, or the right of any group to run a religious university, was less important than the fact that this would somehow discriminate against gay, sexually active students.
