The Supreme Court Friday quashed criminal proceedings against Shiromani Akali Dal (SAD) patriarch Parkash Singh Badal, who died two days ago, and his son Sukhbir Singh Badal in a forgery case, saying the summon order issued by the trail court was "nothing but abuse of process of law". A bench of Justices M R Shah and C T Ravikumar, which had reserved its verdict on a batch of pleas filed by Badals and senior Akali leader Daljit Singh Cheema on April 11, quashed the summons issued by the Hoshiarpur trial court in Punjab and upheld by the Punjab and Haryana High Court.
