The manner of my arrest was illegal — no grounds were communicated to me, no arrest memo was prepared and I was not informed of my right to inform a relative. Can procedural illegalities in the manner of arrest be raised as a ground affecting the admissibility of evidence obtained thereafter and ultimately the conviction in Kolkata?
If your arrest in Kolkata was carried out improperly, whether without following mandatory procedure or without valid justification, this can genuinely become an important part of your defence, though it's worth understanding precisely how such challenges work within a criminal trial. An illegal or irregular arrest, by itself, does not automatically result in acquittal, since Indian courts have consistently held that the manner of arrest and the question of guilt are, in principle, separate issues; however, the circumstances of an improper arrest can significantly affect how much weight certain evidence is given, and in some cases, can lead to evidence being excluded altogether.
The Supreme Court's guidelines in D.K. Basu v. State of West Bengal, along with the safeguards under Sections 41 and 41A CrPC (now the corresponding BNSS provisions) regarding when and how arrest can be made, are frequently invoked in Kolkata courts to challenge the legality of an arrest, particularly where police failed to record grounds for arrest, didn't inform the accused of the reasons, or bypassed the requirement to first issue a notice for appearance in cases where custodial arrest wasn't strictly necessary. Where such violations are established, courts have sometimes granted bail more readily or viewed the prosecution's case with additional scrutiny.
Where circumstances of arrest can more directly influence acquittal is when the illegality taints the evidence gathered as a direct consequence, such as a confession extracted during an unlawful detention, or evidence recovered through procedures that violated the accused's fundamental rights during that period of illegal custody. In such situations, your defence can argue for exclusion of that specific evidence, which may weaken the prosecution's case enough to affect the final outcome.
Because the relationship between an improper arrest and its impact on your actual defence requires careful legal argument connecting the two, this isn't something to raise as a standalone technical point without proper framing. Aapka Legal Advice can help assess how the specific irregularities in your arrest can be woven into a coherent defence strategy.
