My sister in law has filed false dowry, DV case against my brother (her husband), my parents, myself (elder unmarried sister), my married elder sister and her husband - even though she stayed with us for only 7-8 months after marriage and after that had been staying in separate house with my brother for last one year. My sister and her husband stay separately and my brother in law visits our house on few occasions. - still she filed complaint against them also. CAW cell proceedings have not worked out and IO has indicated moving to next level which means my sis - in - law will press charges/file FIR. Is there any recourse by which we can at least get police to exclude name of my elder married sister and her husband since they are staying separate and very little interaction with my sis-in-law?
