An attorney who sued to be a delegate to a possible New York constitutional convention lacks standing to challenge the constitutionality of a law requiring him to be affiliated with a political party to be placed on the ballot, a federal appeals court ruled.

Evan Davis, of counsel to Cleary Gottlieb Steen & Hamilton and manager of a committee campaigning for a convention, argued that he was injured by a requirement that would-be delegates appear on the ballot alongside the name and emblem of a nominating body.

In November, New York voters will be faced with a once-every-20-years vote on whether the state should hold a constitutional convention. It has not held one since 1967.
