Terminating a lease due to no certificate of occupancy

I do not know how the landlord could have complied with the registration requirements of N.J.S.A. 46:8-27 et seq which requires all landlords in the State of NJ to register his/her property with the municipality wherein the property is located.  The first thing the municipality would have required is a certificate of occupancy.  I believe your lease is illegal and that if you notify the landlord he/she may let you out to avoid any legal problems with the municipality.
