Ales said that the board "informed us last week that they would not repeal the policy" but would recommend that the student council do so.
The pro-life group also said it has twice submitted motions to the student body to allow its affiliation, but "on both occasions … our motions were decisively defeated by the students in attendance."
"It was disconcerting to watch our fellow students affirm and uphold our legal disenfranchisement, but it serves as proof that student democracy at Aberdeen is broken, serving only to insulate students from dissenting opinions."
Ales stated that "at this point, all good faith avenues for resolution have been exhausted and ALES is now forced to turn to the legal system for restitution and vindication."
Ausa has stated that it cannot comment on Ales' legal action, but that the group "were invited to re-apply for affiliation as an Ausa society, with the reassurance that the application would be treated in the same way as any other," but that "no application has been received."
A spokesperson for the the University of Aberdeen commented that it is "an inclusive community and recognises different beliefs, values and cultures."
Pro-life groups at other Scottish universities have faced similar problems.
Last year the the University of Strathclyde (in Glasgow) lifted a similar ban on pro-life groups, following legal pressure. Strathclyde Sudents for Life argued that the student associaton's no platforming policy violated the Equality Act 2010 "by directly discriminating against a group of students based on their beliefs."
Glasgow Students for Life were barred from affiliation by the Glasgow University's Students' Representative Council last November.
In March 2018 a joint committee on human rights of the UK parliament noted troubling barriers to free speech at the nation's universities, writing: "Whilst the original intention behind safe space policies may have been to ensure that minority or vulnerable groups can feel secure, in practice the concept of safe spaces has proved problematic, often marginalising the views of minority groups."
