The judiciary is where disputes regarding the actions of the executive branch, whether at the national or level are addressed. If and I emphasis the "IF" there is wrong doing by the executive department, the court serves as the check & balance to those actions.I'm not talking about the judiciary. I'm talking about the local executive branch, like police, city councils, and other minor functionaries who rule over their little fiefdoms.
The public can and should mate change within the executive branch to issues that are perceived to be wrong, but the court does provide an alternative, if necessary.
