As with all civil law it comes down to reasonableness which is undefinable until someone goes to court.
Is it reasonable to prevent someone with a disability from using a buggy because they don't have a doctor's certificate? That's the question the judge ill essentially rule on, helped with other case law.
For me (although the judge may disagree) conditioning their disability policy on the production of certificate is not reasonable, if he had lost it, or just gone out for a quick 18 and forgotten it then the course policy stops him from playing
Good summary
In the absence of a medical cert what would it be reasonable for the club/council to do (not looking to argue as I think you've nailed the case) just can't think of the alternatives
Edit: If it makes any difference, he seems to be calling it equipment while the council are calling it transportation
