I will add to the comments of the noble Baroness, and declare an interest as the chancellor of a moderately well-known university.
A university does not need legal advice in this case to defend freedom of research or expression; all it has to do is stop its subscription to the QAA—the Quality Assurance Agency for Higher Education—which only recently produced advice on the curriculum which was like a parody of an article in the Daily Mail. Among other things, it included the decolonisation of not just music—I entirely endorse what the noble Baroness has just said—but the maths curriculum. Clearly, the people who wrote it had never heard of Arabs, Indians or the Mayan civilisation, which was doing advanced mathematics before Christopher Columbus arrived. All that any university has to do is what Oxford has done—withdraw its subscription to the QAA, which is now pretty well on its last legs anyway. I regard the QAA’s advice to universities as in many respects the most dangerous assault in the last few years on freedom of expression and research at universities. It is crazy time—it is critical race theory canonised. Universities should denounce it with great enthusiasm.
