Key legal question
Whether applying the 1997 cemetery regulation to pre-existing concession terms was unconstitutional retroactivity or arbitrary.
Extracted holding
The immediate application of the new time limits to ongoing concessions was permissible as improper retroactivity and was not arbitrary.
Extracted reasoning
The old duration rules were not acquired rights; the regulation validly modified durable administrative effects. The public interest in sufficient cemetery space and the elapsed time justified adapting existing concessions.
