One possibility would be to use juries to just decide facts, then a panel of judges applies the law to those facts. If there are many factual disputes in a case maybe use multiple juries with each jury only deciding on a subset of the facts, chosen so that no jury sees the entire case. They are less likely to be biased if they don't see the entire case.
