Gitanjali J Angmo, wife of activist, environmentalist and innovator Sonam Wangchuk, has approached the Supreme Court challenging his detention under the National Security Act.
The plea filed through advocate Sarvam Ritam Khare was filed on October 2.
It is not clear when the petition would be heard since the apex court is on vacation this week for Dussehra.
Wangchuk was arrested from Ladakh on September 26 and is currently under detention in a jail in Jodhpur.
The arrest was made pursuant to the protests and violence that broke out in Ladakh over demands of statehood for the Union Territory.
