The company isn't registered as a member of PHASA and I can't find any mention of individual names on the company website, so it looks like they're probably not members of the association.

Also as you don't know where it was filmed and there's no proof that what was done was actually illegal (albeit immoral and unsportsmanlike) you probably couldn't bring a case anyway.

I find it astounding that the client permitted himself to be filmed taking part in such a disgracful act. - I guess he's probably out ther somewhere boasting to his friends how he faced down and killed a ferocious Lion in the jungles of Africa with nothing more that a bow and arrow.

Ah well, I guess some people just suffer from chronic assholism.
