The state government challenged the High Court order staying the remand of Kovan to police custody.
54-year-old Kovan, propagandist singer of ultra-Left arts and literary outfit 'Makkal Kalai Ilakkiya Kazhagam', was arrested in Tiruchirapalli on October 30 for alleged sedition, uploading "defamatory" electronic content against Chief Minister J Jayalalithaa and "disturbing public peace".
On November 7, the Madras High Court had stayed a local court order remanding Kovan to police custody for two days, saying it was 'erroneous'.
The alleged defamatory content in the form of videos were uploaded on some Tamil websites which had gone viral in messaging mediums like Whatsapp.
The content, though centred over the liquor vending policy of Tamil Nadu government, allegedly had direct references to Jayalalithaa, showing her in a bad light.
The HC had said a perusal of the papers revealed that in permitting two-day custody to Kovan, the primary concern of the lower court had been the need to probe any link with the Naxals.
