The rules are being forced through the Parliament by a ruthless and determined EU Commission
That is complete and utter garbage. This is just the normal legislative process being followed. With this type of legisaltion the Commission has to refer it to the European Parliament for scrutiny. The Parliament then has three months to consider matter and, if it deems it appropriate, to adopt a motion to oppose the adoption of the Regualtion.
It is the Parliament and not the Commission which detemines the dates for any debates and votes in the Parliament. I imagine it is fairly common for a motion to be refered to the next plenary session after it has been agreed by the relevant committee.
My understanding is that the three month scrutiny period ends in three weeks time. If the vote is not taken this week then there is only the plenary session in the week beginning 21 October in which a vote could be scheduled. You also have to remember that this will be only one amongst a very large number of issues under consideration by the Parliament that will need to be fitted into the Parliaments schedule. They will all be important to different groups of people.
The absolute majority required to prevent the adoption of such Regulations is again part on the normal legislative process and not something that has been introduced by the Commission for this particular vote.
