Ps seek to challenge a policy by D, in place since 1970, to have all visitors at all times pay an entrance fee. The fee is currently 'recommended' at $25, but visitors may pay as little as 1¢, but they must pay something. Prior to 1970, entry was free to all visitors, at least on certain days and times. Ps claim that they paid for tickets to enter the museum on days and at times that they allege admission was required to be free. Ps allege that D's policy of charging an entry fee, in any amount, separately violates both certain legislation and the lease by which D occupies its home in Central Park. Ps sought a permanent injunction to enforce a free admissions requirement. The lower court dismissed as Ps lack standing. Ps appealed.
