The policy’s one year limitation period “runs from the date of the occurrence of the destructive event or casualty insured against.” General State Authority v. Planet Insurance Company, 464 Pa. 162, 346 A.2d 265, 267 (1975). In General State Authority, the insured’s rental property was destroyed by fire on January 2, 1969, but it was unaware of the loss until May 10, 1971. After the claim was denied by its insurer, the insured filed suit on November 11, 1971. The policy required the insured to file suit “within twelve months next after inception of the loss.” Id. The insured argued that the one year should be measured from the date of discovery. The court held that the limitation does not run from the date the insured discovers the loss. Id.; see also Lardas, 426 Pa. 47, 231 A.2d 740 (<HOLDING>). Contrary to the plaintiffs’ interrogatory
