Everything I find says that to be illegal, something must be against the law, and that a contract is not law, so the word "illegal" doesn't apply to breach of contract because it's private.
There is a difference between illegality and criminality however -- e.g. breaking the speed limit is illegal but it doesn't reach criminal, as one source uses as an example.
