My relative have filed a false case of sec 379 ,323, 501,341 against my dad n mom who are 65+ years of age due to some property issue even though we are equal share holder of the property and not allowing to enter the property and has stppoed the construction (144 sec) ..... Now she used her influence and given 4 witness names in the fir . Current situation is case filed date : 2015 We took bail in 2020 as fir copy submitted by police in 2019 ..chargesheet not yet filed. She has much of influence over getting witnesses pressurize to file fir and all . How to move ahead with this can we move to high court to quas the fir as chargesheet not filed yet and she has filed complaint so that we won't enter the property now
