Hello there!
If a problem cannot be solved using the public policy solution, you can always solve it with a negotiation, this is a direct discussion of differences between parties involved in a dispute, in a way to resolve issues.
Although it should be mentioned that "public policy solution" is the best way to resolve a problem, justice and law will always be the best way. Policy is made in response of an issue or problem that requires attention. Policy is what the government chooses to do or not do about a particular problem.
