Courts can only interpret the laws defined by Congress. There is little they can do if the problem entity X has with entity Y is perfectly legal under the current legal code. Most democratic systems are built this way on purpose, to ensure no one branch of government has too much power. We don't necessarily want the branch in charge of interpreting the law to also be given the ability to write it.
