Whether to excommunicate or not

Maybe it is that it is there somewhere and this writer cannot find it. But is the decree on the remission of excommunication latae sententiae of bishops of the Fraternity of St Pius X (January 21, 2009) in English on the Vatican web site?

Surely one is bound to think again and wonder about all of this. How come just some few short years ago someone is excommunicated and then 'hey presto' the excommunication is lifted?

And what is the truth about the bishop and his statements about the Holocaust?
