Musstt Rehana Begum vs State of Assam & Anr.
Background
The appellant and the second respondent had married in 1996. After she filed a dowry-harassment complaint against him, he purportedly divorced her via a certificate issued through a local Kazi, which she successfully challenged before the Family Court, which declared the divorce null and void and also found that the husband had failed to prove she had an earlier subsisting marriage to another man. Soon after she filed a forgery complaint against him over the fake divorce certificate, the husband lodged a bigamy complaint against her under Sections 494/495 IPC, alleging she had concealed a prior marriage when she married him: the very issue the Family Court had already decided in her favour. The Gauhati High Court declined to quash this complaint, terming the issue "highly disputed."
Decision Breakdown
The Supreme Court held that the Family Court's finding, that the husband had failed to prove the appellant had a subsisting prior marriage, was a conclusive determination between the same parties that had attained finality (the husband's appeal against it having been dismissed for non-prosecution). Relying on its precedents on quashing FIRs/complaints (including Neeharika Infrastructure and Bhajan Lal), the Court held that continuing a bigamy prosecution over an issue already conclusively decided in the appellant's favour by a competent court would amount to abuse of the process of court. It therefore quashed the complaint.
Lesson Learnt
Once a competent court (like a Family Court) has conclusively decided a specific factual issue between two parties, such as whether a person had a subsisting prior marriage, that same issue cannot be relitigated through a fresh criminal complaint between the same parties; doing so is an abuse of the legal process that can be stopped by quashing the complaint.
