Many administrative sanctions may be of dubious validity. Through a ruling, the Supreme Court has tightened the requirements for administrative notifications, which could call into question many sanctioning procedures, tax assessments, and administrative files. Failure to comply with certain criteria in notifications, such as not including even a very short or summarized description of the reason for the notice, can invalidate the procedure, warns Unive Advocats, a specialized law firm. The ruling indicates that the high court's decision can be applied generally, regardless of the procedure or subject matter. This extends its scope to administrative sanctions, tax proceedings, traffic fines, and immigration procedures, among others. According to the lawyers, simply including the file number in the delivery notice is insufficient to interrupt the procedural deadlines. "It is not enough to prove that an attempt was made to notify; it is essential to demonstrate that this attempt met minimum guarantees of providing information to the citizen," such as a description of the reason, the firm emphasizes.
