Dissent is not welcome, when it comes to the ECB.
The expression of a dissenting opinion, especially when the opinion coincides with the view of a large part of the population of the respective country, generates the impression that discussions within the Governing Council are politicised, and that all members reflect national views. This may encourage pressures by national constituencies on the different ECB Council members to act on the basis of national interests, rather than the broader European ones. It may also encourage some national central banks to publicly express views on monetary policy issues, which is against the letter and the spirit of the Treaty because monetary policy is not anymore a competence of the NCBs but only of the ECB. The Treaty clearly states that the ECB Council members should not be influenced by any national or European institution, not even their own central bank.
