Rights upon recusal of judge

I have recently been successful in having a judge recuse himself from my case. What are my rights upon this recusal? Do I have the right to know the hows and whys for this recusal? What about pryer decisions made by this judge? Are they a nullity and void?? Do I have the right to have previous orders, judgments reheard? I would appreciate any eye opening advice, information anyone has to offer. Thank You. Jeff
