I've edited the original post to correct a minor error in the description of the play, which explains where South's other club went. It doesn't change the general principle of the ruling.
East is a very good player, the best player at the table. West is also good, regularly plays for the county first team. EW, particularly East, have a tendency to protracted thinking, and had already lost a board on an earlier round to slow play. South, despite his play to trick one, is also a good and experienced tournament player.
I was the playing director, and overheard raised voices from this table, including South calling East or East's actions "most unethical" and East saying in frustration "OK, you can have the trick then", before I was called.
I calmed them down and did my best to establish what had happened, without looking at the hand, which I had yet to play. I said I would look at the hand afterwards and give a ruling.
I think East was genuinely trying to speed up play when he made his comment, and was not trying to influence his partner. I think he is used to playing in more expert circles where his claim would be readily accepted. I thought it very likely that West would keep his clubs, but still, it doesn't seem right to allow East to make sure he gets the defence right.
As mrdct says, East's comments obviously constitute a claim, and law 70D2 says that his claim that West will keep clubs cannot be accepted if there are alternative normal (including careless and irrational) plays.
West said that he knew which cards to keep. He knows South has
♣A from the play at trick one, and knows his partner has
♥K as that would give South too much for his pre-emptive opening. He also has a count on the heart suit from partner's spot card.
I thought it was a close decision, but in the end I decided that for West to discard a club was "careless or inferior" rather than abnormal, and I awarded declarer the remaining tricks. I could not argue with a director who gave EW a further trick. Even good players make bad mistakes sometimes, and where West's actions are based on partner's signals and assumptions about what declarer would do there seems to be some room for doubt.

A defender can't claim for his partner.
What Law says that?
Isn't this the wrong question? I thought the principle was that anything not sanctioned by the laws is not permitted. The fact that there's a law which tells you what to do if a defender claims for partner does not mean that it is allowed, any more than the existence of law 27 gives players permission to make insufficient bids.
