Section 50

Except as provided in subsection (2), the Commissioner shall take such steps as he may consider necessary to remove or abate all nuisances of a public nature and may, if he considers that the circumstances so warrant, proceed at law against any person committing any such nuisance.

Where any nuisance specified in section 51(1)(a), (e)(ii), (e)(iii), (f), (g) or (k) arises from any want or defect of a structural character, the Building Authority shall take such steps as he may consider necessary to remove or abate the same and may, if he considers that the circumstances so warrant, proceed at law against any person committing any such nuisance, and for this purpose every reference to the Commissioner in sections 52(1), (2) and (4), 53(1), (11) and (14), 54(1) and 55(2) shall be construed as a reference to the Building Authority.[51
