Counsel for both COPA and Wright this week tried to undermine expert witnesses for the other party, particularly questioning their “independence.” Wright’s team on Monday questioned COPA expert witness Patrick Madden on why he’d enlisted the help of COPA’s counsel at Bird & Bird LLP to organize the findings of his investigation into Wright’s claims instead of seeking independent help. On Wednesday, the COPA camp, in turn, asked Wright’s expert witness ZeMing Gao, who has authored multiple essays asserting Wright is Satoshi, whether he was truly an objective expert.
