Rocca v. Thompson

Background

An Italian citizen who lived in California died in San Joaquin County leaving personal property. His widow and heirs were minors and lived in Italy. The Italian Consul General applied for letters to administer the estate, and the county public administrator made a competing application. California trial and supreme courts held the public administrator was entitled to administer the estate instead of the consul, and the case reached the U.S. Supreme Court for review.

Reasoning

The Court focused on whether a mid-1800s Argentine treaty provision giving consuls the right “to intervene in the possession, administration and judicial liquidation” of estates meant consuls could take original administration, and whether an Italian treaty’s most-favored-nation clause imported that right. The Court explained that “intervene” normally means to join or protect an existing proceeding, not to supplant local law. It reviewed U.S. consular statutes and regulations showing consuls act as temporary conservators—guarding, inventorying, and transmitting property—rather than permanent administrators. The opinion noted other treaties that explicitly grant consuls appointment powers when that was intended, and said the Argentine treaty did not clearly remove a State’s local probate rules.

Real world impact

The Court affirmed California’s ruling, putting primary authority over probate for residents’ estates with state law processes and public administrators unless a treaty clearly says otherwise. Consuls retain rights to protect and inventory property, observe proceedings, and transmit funds, but cannot automatically replace local administrators. The Court did not need to decide whether the most-favored-nation clause applied in full.
