The Zoning Hearing Board or the hearing officer, as the case may
be, shall render a written decision or, when no decision is called
for, make written findings on the application within 45 days after
the last hearing before the Zoning Hearing Board or hearing officer.
Each decision shall be accompanied by findings of fact and conclusions
based thereon, together with the reasons therefor. Conclusions based
on any provisions of this chapter or of any act, rule or regulation
shall contain a reference to the provision relied on and the reasons
why the conclusion is deemed appropriate in the light of the facts
found. If the hearing is conducted by a hearing officer and there
has been no stipulation that his decision or findings are final, the
Zoning Hearing Board shall make his report and recommendations available
to the parties, and the parties shall be entitled to make written
representations thereon to the Zoning Hearing Board prior to final
decision or entry of findings, and the Zoning Hearing Board's decision
shall be entered no later than 45 days after the decision of the hearing
officer. Where the Zoning Hearing Board has power to render a decision
and the Zoning Hearing Board or the hearing officer, as the case may
be, fails to commence, conduct or complete the required hearing as
required by this chapter, the decision shall be deemed to have been
rendered in favor of the applicant unless the applicant has agreed
in writing or on the record to an extension of time. Nothing in this
subsection shall prejudice the right of any party opposing the application
to urge that such decision is erroneous.
