Judgement aggregation has been receiving increasing attention over recent years.
Some typical impossibility results have been proved, about majority and other
similar aggregation methods. Those results depend essentially on certain logical
constraints borrowed from standard two- valued deductive logic. Nevertheless, the
adequacy of these constraints is doubtful. In this paper, we show that by
weakening the consistency conditions in a plausible way, such impossibility
theorems can be reversed. We also show that the formalism habitually employed
in social choice theory may convey a richer setting for analysing this sort of
aggregation.
