Mr. Tripolitsiotis has also represented a premier New York City real estate developer in various matters, a Brazilian asset manager in its dispute over ownership rights in Brazilian telecommunication companies, and a major motion picture company in potential litigation against a former partner.

Mr. Tripolitsiotis is the author of a seminal article on Compact Clause entities that was published in the Yale Law & Policy Review and he has consulted on issues related to the compact clause of the U.S. Constitution.
