The Delhi Police had last year filed the charge sheet at a city court against Kanhaiya Kumar and others, saying he was leading a procession and supported seditious slogans at an event in February 2016.

It also charged former JNU students Umar Khalid and Anirban Bhattacharya with allegedly shouting anti-India slogans during the event to commemorate the hanging of Parliament-attack mastermind Afzal Guru.

The prosecution sanction was granted nearly a year after a city court asked the Aam Aadmi Party (AAP) government to take a decision within a reasonable timeframe and noted that the delay was leading to violation of the due process of law.
