how long did last court case take?

Does anyone know how long it took to resolve the last case in which Sumitomo lost in the Solomon Island's?

Am trying to get a rough time frame of how long this will take from the stated court date.

PS. I wonder what Sumitomo will do if they lose in court...walk away losers for the second time or hostile take over...hmmm

I can imagine their argument.
Sumitomo: "we want the rights to the resource, we have the Japanese govt behind us"
Judge: "the land owners have the final say and gave the rights to Axiom KB. Of course the Japanese govt is behind you, they own a large portion of your company...so what's your point? Class dismissed"
