Recently the MtGox civil rehabilitation trustee, Nobuaki Kobayashi, announced a six month delay in proceedings due to disapproved claims still being disputed. The trustee doesn't refer to it directly, but the elephant in the room causing this delay is Peter Vessenes' CoinLab, who after a failed partnership attempt with MtGox in 2012/2013 is now demanding an outrageous $16B USD from the MtGox civil rehabilitation estate.
There have been various theories floating around how CoinLab could possibly be justifying this number, with little insight into their actual arguments, a problem not helped by CoinLab's attempts to seal official Japanese creditor records in order to conceal their actions. Recently though I acquired a copy of the last round of petitions to the Tokyo District Court, and have spent the last week dredging through the legal Japanese to get to the bottom of the situation.
