The Institute for Justice litigates to protect the constitutional rights of all Americans. IJ defends ordinary people who want to earn an honest living, own and enjoy their property, speak freely, and give their children a good education but find that the government is standing in their way.
We fight to hold government officials accountable when they violate constitutional rights and to prevent governments at all levels from bending the rules to expand their power or advance illegitimate ends.
IJ wins three out of four cases through outright courtroom victories or legislative change prompted by our lawsuits.
