A US bankruptcy court has rejected a filing from Seattle-based digital currency service CoinLab Inc. in the latest development in the case of failed Japan-based bitcoin exchange Mt. Gox.

CoinLab sought to stop investor group Sunlot Holdings from purchasing Mt. Gox in documents filed during a 27th May hearing in US Bankruptcy Court in Dallas, Texas.

According to The Wall Street Journal, CoinLab’s filing was complicated when Mt. Gox’s lawyers stated that the deal involving Sunlot had not been given any special status by the courts, and that as such, other offers regarding the ownership and management of the exchange may be considered.

Notably, the decision by Judge Stacey Jernigan could open the door to more purchase bids for Mt. Gox, including one from CoinLab itself.

CoinLab's filing seemingly aimed to stop or at least delay an effort by SunLot Holdings, a group of investors that includes venture capitalists John Betts and William Quigley and the Bitcoin Foundation's Industry Director-elect Brock Pierce, from purchasing Mt. Gox and its related liabilities.

In its filing, CoinLab said that Sunlot’s bid to purchase Mt. Gox was not qualified to handle the investigation required to seek the location of the failed exchange’s missing bitcoins, explaining:

Additionally, the company objected to the investor group’s plan to retain a portion of any funds recovered from Mt. Gox and its related entities during any forthcoming discovery.

Perhaps most notably, the courts indicated, for the first time at least explicitly, that other offers for the exchange can be considered, a statement that may lead to more investor interest in Mt. Gox.

For example, a team involved with Chinese exchange OKCoin has expressed interest in buying the defunct exchange. However, it remains unclear if the group is still actively developing an offer.

Additionally, CoinLab may ultimately submit a formal offer to purchase Mt. Gox.

In court documents, the company suggested, but stopped short of saying outright, that it would seek to buy Mt. Gox, remarking:

Previous statements from Nobuaki Kobayashi, the Japanese bankruptcy official overseeing the case indicated earlier in the day that the Japanese courts – which will have final say on approving any measures – are not presently considering any investor proposals.
