The court was also informed by Puri that he has got interim protection from arrested in the case by the Delhi High Court.
However, the ED opposed the application saying its sole purpose was to create confusion.
"We are opposing the stay on NBW. This is just to create confusion by filing multiple applications. Ratul Puri e-mailed on August 15 to join the probe. Now we will take our call... We called him regularly to join the investigation but he did not come," the agency said.
The court has fixed August 19 as the next date for hearing further arguments on the application.
The ED said that it will file a detailed reply to the application on the next date of hearing.
The court had earlier issued NBW against Puri while noting the ED's submissions that the businessman might try to tamper with evidence and influence the witnesses "as he already did earlier".
The case pertains to alleged irregularities in the purchase of 12 VVIP choppers from Italy-based Finmeccanica's British subsidiary, AgustaWestland.
The deal was scrapped by the NDA government in 2014 over alleged breach of contractual obligations and charges of payment of kickbacks for securing the deal.
According to the ED, the proceeds of the crime have been deposited in the accounts of different companies owned by Puri and he is a key link to unearth the modus operandi adopted by the other accused and to determine last-mile connectivity of the proceeds.
