I hadn't heard about the Law preference ... thank you for that.

And yes, I agree, that winning over the Catechism translation empowered the literalists to move into taking over the liturgy translation as well. 

In fact, it didn't seem to me there was a "dispute" over the Catechism translation; more of a simple coup. I was working for one of the publishers lined up to publish the Catechism in English. All we were told (this at the point when the pages were completely ready to go to press) was: "do not publish that translation ... wait until you receive the authorised translation will".
