The non-obstante clause in Section 144(1) of the Negotiable Instruments Act, 1881 expressly overrides…

Section 144(1) opens "Notwithstanding anything contained in the Code of Criminal Procedure, 1973", so its special modes of serving summons by speed post or approved courier override that Code's ordinary rules. The Civil Procedure Code, the Penal Code and the Evidence Act are not mentioned.

Current law: the Bharatiya Nagarik Suraksha Sanhita, 2023 replaced the Code of Criminal Procedure from 1 July 2024, and the section's reference to the 1973 Code is now read as a reference to the BNSS (section 8, General Clauses Act, 1897).
