Sinhala: එම් ඒ සුමන්තිරන්, romanized: M A Sumanthiran) born 9 February 1964) is a Sri Lankan Tamil lawyer and politician. A successful civil lawyer who practices civil litigation, human rights and constitutional law, Sumanthiran has served as Member of Parliament from the Jaffna District since 2015 and National List from the 2010 to 2015 from the Illankai Tamil Arasu Kachchi.[1]
Sumanthiran was called to the bar in 1991.[4] He then started practising law in Colombo, appearing in civil litigation cases in the supreme court, court of appeal, commercial high court and district courts.[4] His successful cases include the privatisation of Sri Lanka Insurance Corporation, privatisation of Lanka Marine Services and the closure of Pramuka Bank.[4] He has appeared in a number of fundamental rights cases and judicial reviews of parliamentary legislation and executive action including the charging of levy for water and establishing a revenue authority.[4] He prevented the forced expulsion of Tamils from Colombo and successfully challenged an anti-conversion bill which the courts struck down as being unconstitutional.[4][8] He has also appeared for petitioners against the proposed 18th and 19th amendments to the constitution which were found to be unconstitutional and required two-thirds majority in Parliament and a referendum.[4][9] He has worked on a number of public interest cases including the ongoing attempt by residents of the Valikamam North High Security Zone to get their land back from the Sri Lankan military.[4] His human rights work has led to him being threatened, harassed and branded "traitors in black coats" by the Sri Lankan military under the then President's brother Gotabhaya Rajapaksa.[10][11][12]
In January 2017 the Sri Lanka Police's Terrorist Investigation Department (TID) arrested several former members of the militantLiberation Tigers of Tamil Eelam (LTTE) in connection with the attempted assassination of Sumanthiran.[28][29] It was alleged that two aborted attempts were made to assassinate Sumanthiran on the B402 Soranapattu-Thalayadi Road near Maruthankerny on 12 December 2016 and 13 January 2017.[30][31] Five former LTTE cadres - Mariyanayagam Lewis Ajanthan/Louis Mariampillai Ajanthan (alias Jana, Kadalavan) from Championpattu, Maruthankerny; Karalasingham Kulendran (alias Master, Cholai) from Kilinochchi; Murugiah Thavaventhan (alias Vendran) from Kilinochchi; Chandrasekaralingam Vasudevan/Gnanasekaralingam Rajmathan (alias Mathan) from Trincomalee; and Velayanthan Vijayan from Mannar - were charged with possession of explosives and narcotics but the TID informed the magistrates court in Kilinochchi that there had been a plot to assassinate Sumanthiran.[28][32][33] The five suspects were bailed in September 2017 by the High Court in Jaffna .[34] The suspects weren't initially charged under the draconian Prevention of Terrorism Act (PTA) but in July 2018 they were indicted under PTA regulations at the High Court in Colombo.[35][36][37]
Sumanthiran was re-elected at the 2020 parliamentary election.[38][39][40] The preferential vote count held at Jaffna Central College on 6 August 2020 was marred by violent clashes between supporters of various candidates from various parties.[40] Relatives of TNA candidate Sashikala Raviraj (widow of Nadarajah Raviraj) accused Sumanthiran of interfering on the vote count.[41][42] However, the Center for Monitoring Election Violence, an independent election monitoring body who were present at the count, blamed the incident on lack of understanding of the counting process by candidates and their supporters combined with ability to spread unsubstantiated rumours on social media.[43] Sumanthiran denied the allegations, pointing out the counts were carried out and verified at different locations in each polling division, where counting agents for each candidate were present, before the results were brought to the primary counting centre at Jaffna Central College.[40][44][45]
In January 2024, he ran for the leadership of the ITAK against S. Yogeswaran and S. Shritharan. Shritharan was elected by secret ballot on 21 January 2024.[48]
