I don't need luck but leave the law to the lawyers! Common sense is as valid as any law can be. While the law can be an ass it is more often based on simple common sense.
Two crew ops requires its own sops and should not to be confused with single pilot operations. With two pilot ops are you saying that should a rooky first officer screw up at approach minima that you would just sit there and do nothing unless invited or more likely would you as the captain take over? As captain you are always P1 and the P2 first officer when handling only becomes P1u/s, not the same scenario at all.
It is common sense that in general an instructor in the role should undertake routine checks as required. There is no such thing as P1 u/s in single pilot ops and in the case being discussed. There will always be the potential that the instructor may need to take the control. It should be agreed before flight when and how the takeover of control may be done.
