Appeal to Appellate Tribunal requires FORM HSNS APL-02; acknowledgement with appeal number fixes the filing date. Appeals to the Appellate Tribunal must be filed in FORM HSNS APL-02 with relevant documents, including a memorandum of cross-objections and the decision or order. An immediate acknowledgement bearing the appeal number is issued and its date is the filing date; if a self-certified copy is not submitted within seven days, the submission date of that copy becomes the filing date. An appeal is treated as filed only when the final acknowledgement with the appeal number is issued.
