The Enforcement Directorate on Wednesday urged the Delhi High Court to grant it time to file reply to a plea by Chief Minister Arvind Kejriwal challenging his arrest in a money-laundering case linked to the alleged excise policy scam.

Additional Solicitor General S V Raju, appearing for the agency, said the "bulky" petition was served upon them only on Tuesday, and three weeks' time should be given to bring their stand on record.

For interim relief as well, appropriate time should be given to respond, he said.

Senior advocate AM Singhvi, appearing for the AAP leader, alleged that the request to file response was a delay tactic.

Challenge is to the foundation of arrest and there are several "glaring issues" that need immediate decision by the high court either way, the senior lawyer added.

Justice Swarana Kanta Sharma said she would take up the matter again after some time.

The Aam Aadmi Party (AAP) national convener, who has sought his immediate release on account of the arrest and the subsequent remand to ED, was arrested on March 21 and subsequently remanded to the ED's custody till March 28 by a Delhi court.

On Friday, the trial court had remanded Kejriwal in the ED's custody till March 28 "for his detailed and sustained interrogation".

The ED arrested Kejriwal hours after the high court refused to grant him protection from coercive action by the federal anti-money laundering agency.

The case pertains to the alleged corruption and money laundering in formulating and executing the Delhi government's excise policy for 2021-22 that was later scrapped.
