The Henri & Partners Legacy: A Tradition of Advocacy and Justice
A Jurisprudence of Conviction
The firm **Henri & Partners** draws its identity and strength from the exceptional career of Claude Henry Kleefield, a prominent attorney at the New York Bar. Throughout his professional life, Claude Henry Kleefield distinguished himself through an uncompromising legal courage—never hesitating to challenge the highest authorities and the most powerful figures to uphold the rule of law and human dignity.
His name remains linked to historic legal battles that left a lasting impact:
Against the U.S. Presidency (The Ronald Reagan Administration):** Claude Henry Kleefield led and won a pivotal fight for fundamental rights, defending an African national who had been deported under inhumane conditions—transported in a cattle car. This resounding victory served as a reminder that the rule of law and basic humanity must prevail, even when faced with the executive power of the world’s leading nation.
Against New York Real Estate Giants (Donald Trump):** Long before his rise to the presidency, the real estate developer attempted to forcibly evict the occupants of a New York building, in blatant disregard of the law and court rulings. Claude Henry Kleefield stood with these tenants to ensure their rights were upheld; he secured a favorable outcome, cementing his reputation as an attorney who remained unshakable in the face of economic and financial pressure.
