Usually the judges do not "ignore or modify" the law, but rather "interpret" it in a creative manner. You might use, as an example, the question of "does the US Constitution guarantee the women a right to abortion." Some judges decided that it does, later some other judges decided that it does not. Considering the opposing outcomes to the same question, it's clear some of these were wrong.

In the US, it's usually enforcement that's ignored.

That is why everything is illegal 3x over. If they don't like you, you get farked. If they like you, they just ignore it.

Letter of the law vs. spirit of the law.

One could argue that 'a corporation has personhood' is a technical contrivance that tries to manipulate the letter of the law into achieving a particular outcome. Going with the spirit of the law instead, that argument would never hold water.
