6.It is not in dispute that the eviction petition filed against the petitioners herein, though urged on two grounds viz. wilful default and subtenancy, both the courts below have concurrently found against the landlord, insofar as the ground of subtenancy is concerned and that the landlord has not chosen to challenge such concurrent findings. However, insofar as the other ground viz.wilful default is concerned, the courts below concurrently found that the tenants have committed wilful default. It is seen that the tenants sought to resist the eviction petition by contending that the landlord either refused to issue the receipts for some period or receive the rent itself for other period. They also further contended that the petition filed by them before the learned Rent Controller for deposit of rent into the court in RCOP No.93 of 1999 would justify their contention that there is no wilful default. Both the courts below have concurrently found the first contention that the landlord refused to issue the receipt or receive the rent itself, as not established by the tenants as some receipts marked as exhibits issued by the landlord himself well in advance before the receipt of the rent would show that the landlord was not in the habit of not issuing the receipt, as alleged by the tenants. In respect of the next contention of the tenants that they approached the learned Rent Controller and filed a petition to deposit the rent into the court, both the courts below pointed out that such application was filed by the tenants after the filing of the eviction petition by the landlord.
