match_mp_tac is indeed causing an error because it is not applicable in the other subgoals.

I think the match_mp_tac is causing the error since if I only pop the assumption the tactic works on first subgoal. rw [] \\ (pop_assum (mp_tac)) THEN_LT SPLIT_LT 1 (ALL_LT, ALLGOALS (rw[])) > val it = SG3 ------------------------------------ A1 ==> B1 SG2 ------------------------------------ A1 ==> B1 (A1 ==> B1) ==> B1 3 subgoals : proof On Thu, Sep 20, 2018 at 6:21 PM Konrad Slind <konrad.sl...@gmail.com<mailto:konrad.sl...@gmail.com>> wrote: Seems like the rw[] is breaking the proof into 3 subgoals, and only on the first one is the pop_assum match_mp_tac succeeding. So the proof is failing before it gets to the THEN_LT. Konrad.
