§ 302. Appraisals; prevesting discovery. Real property to be acquired
by the exercise of the power of eminent domain shall be appraised on
behalf of the condemnor by an appraiser. In order to adequately prepare
such appraisal upon which the condemnor's offer is based, the condemnor
shall have the right to inspect such property prior to vesting. The
owner, his agents or employees, tenants or other occupants shall upon
reasonable notice by a written request by the condemnor, provide
pertinent data or information including books and records necessary to
prepare such appraisal. A party affected by such request may, where the
request for such information is objected to as unreasonable or
burdensome, petition a court of competent jurisdiction for relief.

Failure of the owner to comply with this section shall suspend the
condemnor's obligation to make an offer to such owner pursuant to
article three until such time as this information is provided.
