Even after the colonial period, Temple was administrated by a conservative method based on clan system - பண்டு பரவணி ("Paṇṭu paravaṇi"). The வண்ணக்கர் (Vaṇṇakkar, the Batticaloan equivalent post for head of trustee), belongs to
Vellalar caste of
Thambiluvil village played a main role in the administration while "வன்னியனார்" (Vaṉṉiyaṉār - former kinglet of
Batticaloa region) of Karavakupattu, belongs to Paṇikkaṉā matriclan of
Mukkuvar caste supervised the rituals and other main activities of temple. Vaṇṇakkar is expected to be from Kantan kuty, one of the prominent
matriclans of Thambiluvil village. Karavaku Vanniyanar is identified in the name of "Kovil Vanniyanar" during his temple activities. A post named "வட்டாரப் பிரதிநிதி" (Vaṭṭārap piratiniti, Regional representatives) was given to each villages and "Pattus" of Batticaloa, from Panama to Kallady.
Nur Yalman, a Turkish anthropologist observed "Kudukkai Kuruthal", a ritual based on Caste and Clan system, which was observed in another
Thiruppadaikkovil Kokkadichcholai. After the independence of the country, the reliability of
Paṇṭu paravaṇi was questioned in the mid 20th Century and had to face many court cases. Since the old settlement around the temple was started to be distinguished as two villages separately - Thirukkovil and Thambiluvil, where the latter had the post of
Vannakkar, the inhabitants of Thirukkovil raised their voice for the right to rule their own temple. And the old Mattakkalappu Desam divided de facto two new districts in 1961 - one remained in the same name while latter got the name "Amparai". As the capital of newly formed
Batticaloa District, Mamangam, another ancient temple situated near
Puliyantivu, which also celebrated its annual festival on Adi Amavasai, subsequently began to replace Thirukkovil in northern Batticaloa. As the results of these facts, Vaṭṭārap piratinitis north to Kalmunai ignore their responsibilities on temple. At last, Thirukkovil lost its primitive state significance permanently. However, the Vannakkar-based Paṇṭu paravaṇi system still continues compromised along with the modern administration system of President, Secretary and Treasurer in which Kovil Vanniyanar post was integrated into President post. Hence, Thirukkovil Temple could maintain its position as "Tecathuk Kovil" with the homage of the Tamil inhabitants of Southern Batticaloa - known as Ampara District today. They still praise the guardian deity at Thirukkovil and celebrate his Mega fiesta "tīrttam" Festival annually with full of devotion and harmony. ==See also==
