Morphology

null + and + void

Both 'null' and 'void' individually denote lack of legal force, and the coordinating 'and' simply reinforces the same sense; the phrase is a legalistic tautology rather than an idiom. Because the combined meaning is directly derivable from the constituent meanings and follows a common cross-linguistic legal pattern, a B1 learner who knows the parts will understand the MWE.

Etymology

Null and void comes from old legal language where null meant 'no' and void meant 'empty', so judges put the two words together to show something had no power or effect at all. That's why null and void means 'having no legal force'.
