I just finished reading the complaint. Looks like it will, to a considerable extent, turn into a "he said, she said" thing, as I suggested earlier.
One thing is clear: GFGU says that it DID spend the money, but has now put it on its books as a "liability" and will pay it back as soon as possible, with interest.
Among other salient points, SPNG says that the money was indeed paid to GFGU by RME. GFGU says that they'd never heard of RME until the wires arrived.
GFGU also claims that they never received signature pages from SPNG, though they sent SPNG their own. If true, I think that could be an interesting point: if a contract hasn't been signed by both parties, is it effective?
