Robert Vadra, facing Enforcement Directorate probe in cases of money laundering, moved an application in a Delhi court Saturday, seeking copy of case-related documents with the central agency.
Special judge Arvind Kumar posted the matter for February 25.
The application was moved through senior advocate KTS Tulsi.
Vadra, the brother-in-law of Congress president Rahul Gandhi, appeared before the Enforcement Directorate for questioning on multiple occasions in Delhi and Jaipur.
The money laundering cases being probed by the ED relate to purchase of alleged illegal assets abroad and an alleged land scam in Bikaner, Rajasthan.
The court had on February 16 extended the interim bail granted to Vadra till March 2.
The ED case against Vadra relates to allegations of money laundering in the purchase of a London-based property located at 12, Bryanston Square worth 1.9 million GBP (British pounds), which is allegedly owned by him.
The agency has told a Delhi court that it has received information about various new properties in London which belong to Vadra. These include two houses, one worth 5 million GBP and the other valued at 4 million GBP, six other flats and more properties.
Vadra has denied the allegations of possessing illegal foreign assets and termed them a political witch hunt against him.
