Bishop Williamson appears to agree with the Cardinal Thesis narrative, as seen in the short clip below. I always thought the theory to be possible.

What, then, are the implications of Canon 185 of the 1917 Code of Canon Law? I am not a sedevacantist, but the invalidity of a papal resignation under duress is a serious matter.
Canon 185 of the 1917 Code of Canon Law states:
"Renuntiatio ex metu gravi et iniuste incusso, dolo, vel errore substantiali facta, ipso iure irrita est."
Translation: "A resignation made out of grave and unjust fear, deceit, or substantial error is by the law itself invalid."
This canon asserts that if a resignation is made under grave and unjust fear, it is automatically invalid by the law itself. This would apply directly to a papal resignation, ensuring that such a resignation would not be considered valid if it were made under threats or coercion.
