All Good Things...
Worf denies the Pasture entry into Klingon Space and former Ambassador Picard gets Worf to allow them in anyway.
I don't think that counts, the question says "another senior officer", implying at least one of them would still have to be serving in star fleet at the time, and neither were... Also worf wasn't making a recommendation, he was denying entry and he wasn't rejected he was talked into saying yes.
I'm not going to venture a guess myself, though...
