Can a University refuse to consider an appeal where they failed to properly consider the equality act as they only allow appeals on the basis of procedural irregularity??

Following the outcome of a complaint to a University, I wish to appeal the decision. The grounds for appeal are either a) new information that was not available at the time or b) procedural irregularity. In reading the outcome letter, it is clear that they have not properly applied the equality act and related guidance in their consideration of the complaint. Would this come under procedural irregularity?

This is regarding the reasonableness or otherwise of a request under reasonable adjustments. Note this is something that is a fairly standard adjustment in most higher education and other institutions and their own university wide guidance says should happen, but the academic department in question has ignored and argues that the workload is too high or too complex.
