Yes, a criminal court in Kolkata can indeed summon documents from a government department, since courts possess inherent authority under Indian criminal procedure to direct the production of any document that is genuinely relevant and necessary for the fair adjudication of the case before them, and this authority extends to government departments and agencies just as it does to private individuals or entities holding relevant records.

To secure such a summons, a party — whether prosecution or defence — must file an appropriate application before the court demonstrating why the specific government department's documents are genuinely relevant to the matters at issue in the case, and the court will examine this request to ensure it reflects a genuine evidentiary need rather than a speculative or overly broad request that might constitute an inappropriate fishing expedition into government records.

Government departments generally cannot simply refuse to comply with a properly issued court summons for document production, though certain limited exceptions exist for genuinely privileged or classified information where specific statutory protections apply, and in such cases, the department would typically need to formally assert the specific privilege claimed rather than simply ignoring the court's directive, with the court then examining whether the claimed privilege is properly established and applicable to the specific documents in question.

Given the potential complexity involved in properly securing government document production, including navigating any privilege claims that might be asserted, it is important to work with experienced criminal law counsel who can effectively pursue this evidentiary avenue.
