New Jersey Statutes Title 2A. Administration of Civil and Criminal Justice 2A § 42-10.12

a. The tenant attempts to secure or enforce any rights under the lease or contract, or under the laws of the State of New Jersey, or its governmental subdivisions, or of the United States; or

b. The tenant, having brought a good faith complaint to the attention of the landlord and having given him a reasonable time to correct the alleged violation, complains to a governmental authority with a report of the landlord's alleged violation of any health or safety law, regulation, code or ordinance; or

c. The tenant organizes, becomes a member of, or becomes involved in any activities of, any lawful organization; or

d. Judgment under section 2 of this act  1 is entered for the tenant in a previous action for recovery of premises between the parties; shall create a rebuttable presumption that such notice or alteration is a reprisal against the tenant for making such attempt, report, complaint, or for being an organizer of, a member of, or involved in any activities of, any lawful organization. No reprisal shall be presumed under this section based upon the failure of a landlord to renew a lease or tenancy when so requested by a tenant if such request is made sooner than 90 days before the expiration date of the lease or tenancy, or the renewal date set forth in the lease agreement, whichever later occurs.
