The Short Version
No credible legal or historical evidence provided shows that Bombay’s municipal corporation required a permit or license simply to walk on public streets in 1956. The cited laws and materials concern permits for particular street uses (such as structures, encroachments, or temporary occupations) and street-line/building-line controls, not ordinary pedestrian passage. Without a specific 1956 by-law or order imposing a walking-permit requirement, the claim is not supported.
