Attorney General Letitia James’s request seeking a conference before the New York Supreme Court has now been granted.
The NYAG’s office claimed that it had failed to resolve the matter with the digital currency exchange, necessitating the latest legal action.
The plaintiffs have failed to directly tie Bitfinex to the trading accounts accused of manipulation, according to the digital currency exchange.
The suit points to a University of Texas study, which claims that Bitfinex may have used its Tether to buy large amounts of BTC.
The ruling is the affirmation of a decision allowing the NY Attorney General to proceed with its Martin Act investigation of Bitfinex and Tether.
The New York State Attorney General has received approval to further investigate the Tether "stablecoin" and its web of corporate backers.
A blacklisted USDC address can no longer receive USDC, and all of the USDC controlled by the address cannot be transferred on-chain.
The authorities seized BTC, ETH and Tether (USDT) to the tune of $15 million, alongside a McLaren and a Ferrari.
The stablecoin adjusted transaction volume reached $54.9 billion in June, a 13% increase from the $48.2 billion transacted in May.
Tether’s supply increased by over 37% on May 13, with USDT’s market cap jumping to $8.7 billion in seconds as new money was printed.
