1. The existence of a decision does not depend on the form in which it is issued and thus a communication made in the form of a letter may also constitute a decision subject to appeal before CAS. A communication intending to be considered a decision shall contain a unilateral ruling sent to one or more recipients and tending to affect the legal situation of its addressee or other parties. If a body refuses without reasons to issue a decision or delays the issuance of a decision beyond a reasonable period of time, there can be a denial of justice, opening the way for an appeal against the absence of a decision. A decision from FIFA or one of its juridical bodies not to open a disciplinary procedure – or the mere absence of any reaction – must therefore be considered as a decision which is final within FIFA. It is thus subject to an appeal with CAS. There can also be a decision where the body issues a ruling as to the admissibility or inadmissibility of a request, without addressing the merits of such request.
