I used to work in quality control at a manufacturing plant. Parts produced in the machine shop were inspected to certify that they matched blueprint specs. Sometimes you would hear someone joke that the part is OK but I’m rejecting the blueprint. Sometimes it was NOT a joke, the blueprint was wrong but the machine shop had ignored it because they knew how the part was supposed to be made. Nullification is the legal equivalent of accepting the part (the action) and rejecting the blueprint(the law). Sometimes the blueprint is wrong but the part is OK.
Good analogy. As a former carpenter I am very familiar with nullifying blue prints. LOL
