If for some reason, the court said, the appeal against the EC order could not be disposed off by the High Court in four weeks, the EC should pass an order allotting a common symbol to Dinakaran's AMMK.
The top court's direction came on an appeal by Palaniswami challenging the March 2016 interim order of the Delhi High Court asking the EC to allot a common symbol to Dinakaran's group.
While disposing off the appeal by Palaniswami, the top court virtually upheld the High Court's interim order and asked the EC to decide the allotment of a common symbol as per the High Court's order.
The AIADMK had split into two groups and both claimed the two leaves election symbol.
The Election Commission recognised Palaniswami's group as the real AIADMK and gave it the two leaves symbol.
