Pennsylvania Motion to File Nun Pro Tune is a motion that allows a party to file a document or pleadings after the relevant filing deadline has expired. It is an equitable remedy that allows the court to overlook the late filing and consider the document as if it were filed on time. The motion must be accompanied by a brief, supporting affidavit, clearly explaining the circumstances that led to the late filing, and must include an argument for why the court should grant the motion. There are two types of Pennsylvania Motion to File Nun Pro Tune: one for filing a document after the relevant filing deadline has expired, and one for filing a document after the court has issued a final ruling. The former is usually granted when the court finds that the party acted in good faith and that there was a reasonable explanation for filing the document late. The latter is more difficult to obtain, as it requires a showing of extraordinary circumstances, such as an unforeseen emergency or mistake.
