A case has been filed against Sharif Brothers as they are considered responsible for the Model Town Incident by certain quarters in Pakistan. There are many quarters in India and Indian living outside India who consider Modi butcher of Gujrati Muslims.
In other words, you are proving that Pakistani courts act more rapidly than Indian courts to accept cases against anyone, be it a CM and PM. There is some problem with the judicial system in India that Muslims got no relief either in Babri case or riots in Gujrat.
As @Southie uncle put it in another thread ‘the situation is quite depressing’. I really pity Indian Muslims who consider their butchers their messiah. I find Indian Muslim weaker than Sindhi Hindus who can raise voice against PPP government in Sindh.
