A summons keeps the investigation non‑custodial, so the accused stays free, appears when called, prepares with a lawyer, and faces less pressure in questioning, while a warrant brings arrest and possible custody, tightening timelines and increasing the risk of coercive interrogation and bail battles. Best lawyers respond by advising clients served with summons to attend with clear, limited answers, and if arrested on a warrant they immediately assert rights (grounds of arrest, access to counsel, medical check), move for bail or relief from custodial remand, and, where arrest or warrant use was unnecessary or abusive, challenge those steps before trial or higher courts while ensuring the client strictly follows all investigative and court directions.
