Article 55 formally repeals Federal Law No. 7 of 2017 on Tax Procedures and its associated amendments. It also abrogates any other legal provision that is contrary to or inconsistent with the current Decree-Law. However, it establishes a transitional framework where the Executive Regulations of the repealed law, and any decisions issued for its implementation, remain in force. This continuity is conditional upon these regulations not contradicting the new Decree-Law's provisions. They will cease to be effective only upon the issuance of new Executive Regulations and replacement decisions under the new legislative framework.
