A party aggrieved by an order of DHCR’s Rent Administrator (“RA”) may file a Petition for Administrative Review (“PAR”) with DHCR’s commissioner. See RSC §2529. The commissioner’s job is to determine whether the RA — based on the evidence before him or her— reached the correct conclusion. RSC §2529.6 provides:

Review pursuant to this Part shall be limited to facts or evidence before a Rent Administrator as raised in the petition.
