IPC §53A

BNS does not carry an equivalent interpretive rule. The Sanhita does not use transportation as a punishment category and does not need a translation rule for legacy references — the 1955 transition has been operationally complete for nearly 70 years.

IPC Section 53A was inserted in 1955 to handle the transition away from transportation as a punishment: it translated references to transportation for life in other laws to imprisonment for life, deemed references to shorter-term transportation as omitted, and treated pre-1955 transportation sentences as rigorous imprisonment for the same term. BNS does not carry an equivalent interpretive rule. By 2024, the 1955 transition has been complete for nearly 70 years; the interpretive function has been operationally exhausted, and BNS treats transportation as a defunct term outside the Sanhita's vocabulary. This is editorial non-carry-forward consistent with the locked doctrine for omitted transitional rules — no flag fires (not pre_bns_repealed, since IPC 53A was operative until BNS replaced IPC; not definition_externalised, since no other statute is providing the meaning; not consolidation_context, since nothing is absorbed into a BNS structural cluster). Plain no_correspondence.
