No summon to us and decree against us and executed in hast harsh and speedy manner

Dear sir I need a advice and help and lawyer who can help me to get out of this mess . Sir in 2015 SDM in dispute of two parties who have purchased land from my grandfather in 1968 have pleaded to resolve there issue and SDM by his judgement have decided that 2karnal land was more with us and ordered to get the land from us which we came to know when we got judgement it was a big surprise to us that we were not made the third party we were not get listened and decree was executed in very harsh haste and speedy manner , I even wrote an application to tehsildar that my father is out of station and presently in port Blair and the execution may be done thereafter but the execution of decree was done . I than filled a case with DC who said that the area has been de notified and he don't have power to execute the same . I have than filled a case in high court but till date it is pending for 2 yrs. Please guide me as SDM have not only barred natural law of justice but also seized fundamental rights which are right to equality. Please help as the opposite party are politicaly well connected and have influence over the police and local administration. Waiting for an early reply Regards Naveen sangrai
