  In this paper we propose a dynamical approach based on the
Gorini-Kossakowski-Sudarshan-Lindblad equation for a problem of decision
making. More specifically, we consider what was recently called a quantum
parliament, asked to approve or not a certain law, and we propose a model of
the connections between the various members of the parliament, proposing in
particular some special form of the interactions giving rise to a {\em
collaborative} or non collaborative behaviour.
