In principle I agree; however, this South is a fading shadow of a once fine player, who now has difficulty concentrating and is subject to frequent lapses. A PP would be pointless, serving only to punish the partners who make it possible for him to continue to enjoy the game. I shall know next time that I need to watch more closely.
That, of course, calls for leniency.

Incidentally, the ruling is not 100% clear to me. The diamond had already ceased to be a penalty card, and a D lead was prohibited, at the point that the club was led OOT. I ruled that the prohibition remained in place, that the club was now a penalty card, and that the declarer could additionally require or forbid a club lead. An alternative would have been to let him forbid a club OR require a club OR forbid a diamond, with the club remaining a PC in the third case only. This seems to be one of those cases of double infraction that the Laws don't quite address, though of course I may be missing something.
There is no doubt in the laws here and your ruling was as far as I understand quite correct: The prohibition against a diamond lead by North remains in force until a different player has had the lead, and in addition South now has an exposed club to be handled according to Law 50D (single major penalty card).
