The Delhi High Court upheld the validity of Section 311A of the CrPC, clarifying that arrest is not mandatory for obtaining specimen signatures during investigations. It stated that the proviso is directory, not mandatory, allowing individuals to voluntarily provide samples without being arrested. This interpretation aligns with similar provisions in the Bharatiya Nagarika Suraksha Sanhita (BNSS), ensuring investigative efficiency without infringing on fundamental rights.
