Preferential right under Sec 22

Hi Sir, my father and his two brothers have and undivided residential house. The house was buyed by my grandfather and his friend sharing 50-50. Later my grandfather in 1989 died without any will and bot my uncles left the house to stay in their own homes. Later my father buyed the 50% share of my grandfather's friend in 2001. And now my father is owner of 65% and my uncle and the their mother. (Stepmother of my father) owns the remaining 35 percent. Irrespective of giving an offer to buy the remaining share from my uncles they are insisting us to sell all the property. We are staying there and don't want to sell that property. Since last 32 years my father has spent lot of money to repair the house every now and than as it was a old construction. My father as filed a suit U/S 22 of the preferential right to buy the share of my uncles and their mother through court. Which is pending. In the meantime one of my uncle has filed a partition suit to get the property divided. Will we get the possession of whole property under section 22 through the Court. What will the effect of partition suit filed by my uncle. Please suggest.
