Should any section or provision of these requirements contained
herein or as amended, or the application thereof to any person or
circumstance hereinafter, be declared by a court of competent jurisdiction
to be invalid, such decision shall not affect the validity of these
regulations as a whole or any part thereof, other than the part so
declared to be invalid. The Planning Board hereby declares that it
would have enacted these regulations or the remainder thereof, and
the Town Board declares that it would have approved the same, even
if the invalidity of such section or provisions or its application
had been apparent.
