I`ve already done a topic about this under another nick at

What the JAR 145 says is that you stop using the mel after closing doors.
At my actual company, we proceed with the ECAM Ations or QRH ,then go to the FCOM 3 and the MEl in this order.
But we are strongly encouraged to use the mel until a second before TO POWER is aplied.
For you have an idea,in the 320 if you have an ADR#2 failure,you are just requested to turn it off. Normally a pilot could easily think thre is no problem since we have 3 ADR`s but if you go to the MEL you will see that we can`t take off with FLAPS 1+F.
Not to speak the dispatch restrictions you can have at your destination to the way back.
To me this is the most stupid regulation ever written
