Can tenant appeal to higher court without paying the arrears in rent?

we had filed a case on our tanent for non payment of rent in october 2016. we had a registered court agreement. lease is expired in dec 2016.. tenent did not appear in court in any hearing despite judge order. his lawyer came twice. he has admitted that he is tanent and did not give rent for 6 months with false explanations. now decision is coming in next hearing. My question is that our tanent called us and threatening us that he will move to high court. our court is in lower court now. can he move to higher court while he did not attend any hearing here? second question is that can he move to high court without paying arrears of rent and court fee/
