Explained: Why Bharti Airtel, Vodafone Idea shares rallied up to 4% on Tuesday

Bharti Airtel and Vodafone Idea shares gained up to 4% after Bombay High Court quashed the government's one-time spectrum charge demands, providing a combined relief of Rs 20,000 crore to Vodafone Idea and Bharti Airtel. The court ruled the government lacked legal authority to issue the demand notices, annulling all actions taken under them and directing the return of bank guarantees.
