Sure. Which is, again, why this was not an election - the resulting proposal, if any, will need to be ratified by each of the member states. (Which is where elections, referenda etc. come in)
"How and when would these changes become effective?
The European Commission's proposal will now go to the European Parliament and the Council for their agreement.
To allow for a smooth transition, under the Commission's proposal each Member State would notify by April 2019 whether it intends to apply permanent summer- or wintertime. The last mandatory change to summertime would take place on Sunday 31 March 2019. After this, the Member States wishing to permanently switch back to wintertime would still be able to make one last seasonal clock change on Sunday 27 October 2019. Following that date, seasonal clock changes would no longer be possible.
