In Meenan Oil Co., L.P. v. WCAB (Pownall) the Commonwealth Court held that pursuant to Section 413(a) of the Act, a review petition can be filed "at any time" to correct material mistakes including the date of injury and the description of injury.
The key here is the facts that direct the relief requested existed at the time the NCP was issued. The WCJ considered these facts under a review petition. The WCJ's finding that the date of injury and the description of injury were incorrectly entered on the NCP was within the authority granted by Section 413(a).
