(2) If a nonvested property interest or a power of appointment was created before January 1, 1990, and is determined in a judicial proceeding, commenced on or after January 1, 1990, to violate this state’s rule against perpetuities as that rule existed before January 1, 1990, a court upon the petition of an interested person may reform the disposition in the manner that most closely approximates the transferor’s manifested plan of distribution and is within the limits of the rule against perpetuities applicable when the nonvested property interest or power of appointment was created. [1989 c.208 §5]
