The appellant occupied residential property originally owned by his father. After the property was sold in execution to First National Bank, it was transferred to the respondent in 2001. The appellant then leased the property from the respondent but fell substantially into arrears. In 2006 the parties concluded a settlement agreement, made an order of court, cancelling the lease and providing that the respondent would sell the property to the appellant if he paid or secured the purchase price by 31 May 2006, failing which he undertook to vacate by 30 June 2006. The appellant failed to pay or secure the purchase price and refused to vacate. The respondent obtained an eviction order. Only at the stage of seeking leave to appeal did the appellant attempt to rely on an alleged enrichment lien based on improvements to the property and sought leave to adduce further evidence to support that defence.
