Dear Concern,
Please note -
First among all, my apologies that I got hold of this query one day later when it was posted by you. Let me answer one by one as per the Supreme Court style of working -
01. Supreme Court is the appellate court of jurisdiction so it do not go into the facts of the case but in to the legal aspects of the case which has not been dealt by the earlier courts at the time of deciding the case.
02. You can come to Supreme Court only when the matter has been decided by the lower court as well as the High Court. There can't be any appeal before Supreme Court when the case is already pending before either of the courts. As per your query the matter has been decided by the lower court but it do not suggest anything in terms of the High Court.
03. Your possibility of winning a case in Supreme Court depends upon following things -
(i) How well have you contested the case in Lower Court which is the original court of jurisdiction and has the right of appreciating the evidences,
(ii) How well have you contested the case in High Court which is the last court for appreciating the evidence in normal as well as exceptional circumstances,
(iii) How badly your submitted evidences were ignored by the lower court as well as the High Court, and
(iv) How well do you contest the case before the Hon'ble Supreme Court of India by appointing such advocate who has time for your case, looks into the details of the case, can prepare notes and study further if required and is easily approachable as and when required. Normally people instead of looking for these qualities look for the reference passed by whom, number of years spent in the practice, connection and footing which he or she has in court which can be easily compensated if you ask a senior counsel to represent you on the assignment done by your advocate.
04. As far as my experience is concerned, you have a very good case before the Supreme Court of India because -
(i) Majority of the evidence produced before the court were grossly ignored by them,
(ii) The lower court has failed to draw any sort of inference from the evidences produced before them,
(iii) The lower court has gone ahead of the scope of the law while deciding the case of partition. It is settled principles of law that a family settlement in terms of ancestral property is acceptable if things has been undertaken as per that. Your query suggests that majority of your family members have went ahead and sold off their portion as per the family arrangement so that means it was acceptable to them. That should have been acknowledged by the lower court which they have not. And that makes your case for the Supreme Court provided even High Court have refused to acknowledge that.
One can detail remaining things only when he get hold of the documents. If you can pass on the file to any advocate of your choice he will guide you further over this file.
