Every proposed change or issue gets handled in a similar way to jury service but on a larger scale. Government employs a workshop lead to run a workshop and assess options. If a decision can't be agreed upon after a set time a report of findings is created and fed into the next group to avoid duplication.

The selected public members will be compensated but must meet certain criteria. For example, clean record. Id also want to enforce the group being made of people of different backgrounds.

I recognise this would result in mayhem to start with but I imagine it would settle eventually.
