The Delhi High Court today refused to stay Aam Aadmi Party government's plan to impose the odd-even number plate formula for plying of private vehicles from January 1 in the city. <br/><br/>A bench of Chief Justice G Rohini and Justice Jayant Nath declined the request made by one of the petitioners that the court should at least grant stay on the implementation of the government's idea till January 6, which has been fixed as the next date of hearing on the PILs.
