Lex Non Cogit Ad Impossibilia Definition:

Latin: The law does not compel a man to do that which is impossible.

Also rendered et impotentia excusat legem.

Herbert Broom calls this a "fundamental legal principle".

Broom descibes the application of the principle in more detail:

"... that ... where the law creates a duty or charge and the party is disabled to perform it, without any default in him, and has no remedy over, the law will in general excuse him...."
