Other ways you could rewrite it include:

       This was as much the case under ... as under ...
       This was as true under ... as under ...

The problem is that the equative "as ... as ..." construction really
needs both instances of "as" to sound right.  "Equal(ly)", of course,
*means* the same thing, but it's not quite assimilated (the technical
term is "grammaticized") to the requirements of the construction yet,
so we go happily along with "equally the case", and then trip over the
"as" because the first shoe hasn't fallen yet.

This is not unrelated to the problems with the comparative
constructions with "than" or "from".  Most of those arise from new
locutions that are comparative in sense, but not yet in grammatical
rights and privileges.

Equative, comparative, and superlative constructions are among the
hairiest in English, as memorialized in the subtitle of 
Jim McCawley's
The Syntactic Phenomena of English.  He wanted to call it
_More Than You Probably Wanted to Know About English Syntax_.
Try parsing that one and you'll see.
