MOORE, Chief Justice. At issue in this appeal is the constitutionality of a 1992 amendment to the permanent fund dividend (PFD) statutes, Chapter
4, section 4, SLA 1992. The amendment changed the qualifying date set forth in AS 43.23.005(a) for a 1993 PFD. Charles E.
Underwood, Jr., along with his wife and son, Susie G. Underwood and Anthony C. Underwood (the Underwoods), allege that they
were unlawfully denied 1993 PFDs as a result of the change. They instituted this action against the State of Alaska, Governor
Walter J. Hickel and the Department of Revenue (collectively "the State"), claiming that the amendment violated a number of
their constitutional rights and that the State was estopped from denying their dividend applications. The superior court granted
summary judgment in favor of the State. We affirm.
