(b) It shall be unlawful for any person to remove or attempt to remove any tenant or occupant from any housing accommodations or to refuse to renew the lease or agreement for the use of such accommodations, because such tenant or occupant has taken, or proposes to take, action authorized or required by the act or any regulation, order or requirement thereunder.
(c) No tenant of any housing accommodation shall be removed or evicted unless and until such removal or eviction has been authorized by a court of competent jurisdiction.
(d)
(1) In addition to any other limitations imposed by these regulations, no proceeding to recover possession of any housing accommodation based upon any wrongful acts or omission of a tenant, pursuant to section 2504.2 of this Part, may be maintained unless:

(a) the wrongful acts or omission of the tenant pursuant to section 2504.2 of this Part;
(b) the facts necessary to establish the existence of said wrongful acts or omission; and
(c) the date certain by which the tenant must cure said wrongful acts or omission, which date shall be no sooner than 10 days following the date such notice to cure is served upon the tenant.
