Gitanjali J Angmo, wife of activist Sonam Wangchuk — detained under the National Security Act (NSA), 1980, since September 26, 2025 following violent protests in Leh – on Thursday alleged in the Supreme Court that four videos that formed the basis of his detention were not shown to him.On behalf of Angmo, senior counsel Kapil Sibal told a Bench of Justice Aravind Kumar and Justice Prasanna B Varale that only the thumbnails on pen drive were displayed. He asserted that not supplying the videos violated Wangchuk’s right to effective representation before the advisory board as well as the government.”It is now alleged by the State that the DIG came with a laptop and showed four videos. The laptop was provided to detenue on October 5, 2025, but those four videos were not there. Let’s assume they showed it to be; that is not the requirement of law. The requirement is to give it to me. They have to provide the document; I don’t have to ask. It is their constitutional duty to supply. We have said time and again that the four were never supplied,” Sibal said.However, a lawyer assisting Sibal submitted that the pen drive was inserted in the laptop before Wangchuk, and he only saw the thumbnails. “The videos were not actually played. None of the thumbnails were actually clicked,” the lawyer said.Additional Solicitor General KM Nataraj said there’s a video in which the conversation with the DIG and the detenue will show everything.Solicitor General Tushar Mehta said he would need time to respond to the allegations that the transcripts of the videos or statements cited against Wangchuk by the detaining authority were wrong. “There’s a 40-minute video. I have something to say on the contention that the translations are wrong,” Mehta told the Bench.Sibal objected to Mehta’s request for more time, saying the authorities failed to respond to her allegations in the counter affidavit and now cannot be given more time to respond.As arguments remained inconclusive, the Bench posted the matter for hearing on February 23.On February 18, the Supreme Court had questioned the Centre over the transcripts of videos submitted by it against Wangchuk, saying translations should be precise in the age of Artificial Intelligence.The activist was detained on September 26, 2025 under Section 3(2) of the NSA, two days after protests demanding Ladakh’s statehood and the Sixth Schedule status turned violent, leaving four persons dead and nearly 100 injured.The NSA empowers the Centre and states to detain individuals to prevent them from acting in a manner “prejudicial to the defence of India”. The maximum detention period is 12 months, though it can be revoked earlier.Wangchuk had on January 29 denied exhorting his supporters to overthrow the government like the Arab Spring and asserted his democratic right to criticise and protest.The Centre and the Union Territory of Ladakh Administration had sought to justify Wangchuk’s detention under the NSA, saying he was detained for instigating people in a sensitive border area.
