It points out their expressions in official documents, discusses their role in creating legislative momentum for CMU and its individual initiatives, and observes them in the legislative process and content of selected initiatives. The research results include an explanation of the significance of EMU objectives as arguments in debates and decision-making concerning CMU as well as an assessment of their justificatory force.
