A few of the holders of Wentworth grants were from northwestern Connecticut, and some of them were related to Allen, including Remember Baker and Seth Warner. In 1770, a group of them asked him to defend their case before New York's Supreme Court. Allen hired Jared Ingersoll to represent the grant-holder interest in the trial, which began in July 1770 and pitted Allen against politically powerful New York grant-holders, including New York's Lieutenant Governor Colden, James Duane who was prosecuting the case, and Robert Livingston, the Chief Justice of the Supreme Court who was presiding over the case. The trial was brief and the outcome unsurprising, as the court refused to allow the introduction of Wentworth's grants as evidence, citing their fraudulently issued nature. Duane visited Allen and offered him payments "for going among the people to quiet them". Allen denied taking any money and claimed that Duane was outraged and left with veiled threats, indicating that attempts to enforce the judgment would be met with resistance.
