1 Remember that the only people who can make or change laws are the legislators that we elect to local councils and state and federal legislatures. 2  Writing a letter to the President, Governor or Mayor is aiming at the wrong branch (executive)--they only enforce the laws. You may not want to change a law but throw it out altogether. 2  In this case, you'll have to go to court. 3  You can file a lawsuit but the way that most laws are thrown out, or overturned is by a court declaring them unconstitutional.
