Our featured cases
We litigate in state and federal courts nationwide—at the trial, appellate, and Supreme Court levels—to preserve the rights and values embedded in the Constitution.

Our team
We uphold the rule of law.
Every member of our team is driven by a shared conviction: that the rule of law and democracy are inseparable.
A system of laws by which both the governed and the government agree to abide; transparency in the enactment and enforcement of the law; a fair legal system for adjudicating rights and responsibilities; and competent, diverse, independent lawyers and judges – that is the rule of law that ICAP defends.
Mary McCord, Executive Director
