Two points about the concept of an aggregation rule are worth noting.

The premise-based procedure seen in the court's case is an example of an aggregation rule that violates independence.
There is no judgment aggregation rule F that jointly satisfies the above conditions that is not a dictatorship.

Which aggregation rule performs best at 'tracking the truth' depends on the relationship between the individual votes and the relevant fact or state of the world.
The present way of representing an aggregation rule helps us see how many possible aggregation rules there are (see also List 2011).
For generality, the requirement that R be complete and transitive is not built into the definition of a preference aggregation rule.
