The threat of violence against any Honorable Justice of High Courts is not something new for India. Even since the days of #OhSoPeaceful terrorism in the state of Jammu & Kashmir (now a Union Territory), this has been faced by judges who chose to go with the Indian Constitution, instead of bowing down to religious terrorism.
This was something that Kashmiri Pandit, Justice Neelkanth Ganjoo faced when he sentenced the terrorist Makbool Batt for his crimes against humanity in 1968. He was murdered while returning home in November 1989. You can read more about Justice Neelkanth Ganjoo here – https://en.wikipedia.org/wiki/Neelkanth_Ganjoo
Before him, the terrorists had kidnapped and murdered an Indian posted at Burmingham, Ravindra Mahatre (https://en.wikipedia.org/wiki/Killing_of_Ravindra_Mhatre) in 1984 to seek the release of the terrorist Makbool Batt. The same happened when the three-judge bench of the Karnataka High Court said that Hijab is not an essential religious practice. So they denied relaxing the uniform dress code rules for a few privileged girls of a particular #OhSoPeaceful community.
