Director of Litigation, Immigration Reform Law Institute
Mr. Hajec joined the Immigration Reform Law Institute (IRLI) in 2017 as its Director of Litigation, and is responsible for overseeing IRLI’s public interest litigation.

At IRLI, in addition to representing plaintiffs in immigration-related civil lawsuits, he has overseen the drafting and filing of nearly 100 briefs, mostly amicus curiae briefs in defense of the Trump administration’s immigration initiatives, which have been subjected to an unprecedented degree of legal assault by well-funded interest groups.
Prior to joining IRLI, Mr. Hajec was an attorney at the Center for Individual Rights (CIR), where he litigated a string of high-profile cases, including the defense of videographer James O’Keefe in suits brought by former ACORN employees, a class action suit on behalf of Asian American students discriminated against by the New York City public schools, and a case that resulted in the U.S. Court of Appeals for the Fifth Circuit’s striking down Texas’s psychologists licensing statute as an overbroad restriction on free speech.
Before CIR, Mr. Hajec was an officer in the Navy Judge Advocate General’s Corps, where he served as a defense counsel before courts-martial and then as Appellate Government Counsel, arguing over 100 appeals before the Navy-Marine Corps Court of Criminal Appeals and the Court of Appeals for the Armed Forces. He received the Navy Commendation Medal for his legal work, and also because of his poor handling of an emergency during a hurricane.
He received his law degree from the University of Pennsylvania Law School and his undergraduate degree, cum laude, from the University of Michigan. He has a Ph.D. in philosophy from the University of Miami, and studied philosophy and sociology at Oxford University.

He is a contributing author to the Encyclopedia of the Supreme Court of the United States (on Magna Carta). He contributed eight essays to the third edition of the Heritage Guide to the Constitution: five on the amendment procedure and one each on the Guarantee Clause, the Postal Clause, and the Recess Appointments Clause.
