4.The contention that the petitioner and others, being members of an union called Tamil Nadu Electricity Board Workers Progressive Union, are victimized and transferred, have not been proved. Except a representation, dated 22.06.2011, said to have been made by the General Secretary of the said Union, no materials have been placed on record to substantiate the contention that a ruling party member had given a letter to the Chairman of the Tamil Nadu Generation and Distribution Corporation Limited, Chennai, to transfer the members of the above said Union. However, it is well settled that when mala fides are alleged against the authorities or the persons, who are instrumental in issuing transfer order, they should be impleaded as party respondent and the act of mala fide has to be specifically pleaded and proved. When the petitioner has alleged mala fide , on the part of the Chief Engineer (Personal), alleging that an MLA belonging to the ruling party has given a letter, the petitioner ought to have proved the same. Expect the above said letter, dated 22.06.2011, stated supra, there is no other supporting material to prove mala fides .
