Here's my interpretation and possible solution:

...dado que a retroactividade Ihe era favoravel, a ela nas se opondo o comando constitucional constante do artigo 103.
retroactivity was favorable to her, which constitutional rule did not oppose.

a ela não se opondo o comando constitucional = o comando constitucional não se opõe à retroatividade (e a retroatividade é favorável à autora) =

I understand that "retroactivity was favorable to the author and that constitutional rule did not oppose it."
