In the event that during the period of effectiveness
provided for the approval of any application for development, the
developer is barred or prevented, directly or indirectly, from proceeding
with the development otherwise permitted under such approval by a
legal action instituted by any state agency, political subdivision
or other party to protect the public health and welfare or by a directive
or order issued by any state agency, political subdivision or court
of competent jurisdiction to protect the public health or welfare,
and the developer is otherwise ready, willing and able to proceed
with said development, the running of the period of effectiveness
of approval under this chapter shall be suspended for the period of
time said legal action is pending or such directive or order is in
effect.
