This book discusses EU member state institutions that vote either by unanimity or by two-thirds majority

This book discusses EU member state institutions that take all their decisions by unanimity (i.e., individual countries can and do hold all others hostage in order to extract concessions for their vote). On the other end of the spectrum are EU institutions that take most of their votes by so-called qualified majority. In this case, the former hostage holders can now simply be outvoted. Hence, the latter EU institutions could be a likely candidate for a practical solution to the unanimity-voting quagmire.
