Estoppel.
What this section does
When a person has, by declaration, act or omission, intentionally caused another to believe something to be true and act on that belief, neither that person nor their representative can deny the truth of that thing in any suit or proceeding between them. This is the doctrine of promissory or representational estoppel. The illustration shows that a seller who falsely represented title cannot later deny that title to set aside the sale.

Why this matters
BSA Section 121 forms part of Bharatiya Sakshya Adhiniyam which replaced the Indian Evidence Act 1872 on 1 July 2024. Any new filing, FIR, charge sheet, or bail application made on or after that date should cite the new section number. References to the old act in legacy documents remain valid for matters that arose before the changeover.
