You miss the point of the State of Necessity. It is not what the Pope thinks. Canon laws 1321 and 1323 explcitly state that if the individual, right or wrong, believes in all honesty there is a state of necessity, no excommunication applies.
Lefebvre believed the traditional Church was deliberately being destroyed. He saw this as an unparalleled crisis in the life of the Church. By the way, he died in all serenity--even joking with the nurse that since he could take no nourishment, he shouldn't be paying the same rate as someone who had a good appetite. The man was serene in what he did. He has been demonized by his opposition in the Church (we conservatives know how that works) but he was really a great man. He worked in the African missions all his life among the poorest of the poor.

The Pope issued the excommunication under his own authority. Please explain how Canon law trumps the Pope’s authority.

You can’t, because it doesn’t. As silly as the necessity argument is, it isn’t even relevant.
