Thanks for your helpful comment as a setter on 16a. I can see clearly from it what your objections are.

However, the clue still sees acceptable to me.
Bumble, as a literary creation, may have said that the law is ‘a ass’ but countless real people say ‘an ass’ when using the expression.
It is otherwise only the comma after ‘example’ that is misleading, but we are told regularly to avoid paying excessive attention to surface punctuation in ‘crosswordland’.

Re the quotation, I am reminded a little of the arguments about homophones that involve, in my view, too rigid a demand for exact replication of sound in the answers. ‘It’s said’ does not have to mean ‘Bumble says’.

Not quite so keen on this as some other posters. First thing that strikes me is that the ‘for example’ bit should indicate EG as the first two letters of the answer word. Obviously this is not the intended case, which means (as there’s no inclusion-indicator) that this must be an anagram of all the parts, indirectly indicated and thus wrong.

And if we have a quick look at the definition, unless you’re feeling REALLY generous (and some of you are), this part of the clue is also not acceptable. If Gordius had used ‘a ass’ (the correct form of words used by Bumble as noted above) then solvers might have been given a fighting chance despite the poor construction, but unfortunately this did not occur.

Sorry, but that is just an extremely disappointing clue – Hugh’ve been had.

Thanks. Yes I realise. We seem to be having some rather corporal exchanges recently!

… and Kaolin & Morphine works the other way of course, tupu !

The law “it’s (been) said” is a(n) ass.
LEGAL = “of the law”.
Ergo, substituting “an ass” for the law, we get “Of an ass, it’s said…..
I resyt my case.
