Amphastar's attorney was basing his one year to prepare timeline on the difficulty of the discovery process. An indicator that Amphastar intends to stonewall discovery as much as possible, perhaps?
I'm being facetious. This is the sort of inferential stuff that tends to get us in trouble (remember the inferences about Amphastar having no chance for approval?), and I'm not going to put much weight on yours or Clark's or mine in this instance.
