"Shell confirms that it has filed a writ petition in the Bombay High Court challenging the draft tax order," the Anglo- Dutch oil major said in a statement. The company "will continue to evaluate all options for redress available to resolve this tax dispute", it said.
In February, company officials had said that the tax authorities have raised a demand of USD 1 billion (about Rs 5,400 crore) on an equity infusion of USD 160 million (about Rs 870 crore).
Details of the writ petition could not be ascertained.
