What I meant isn't that someone would have decided to start the process again, rather than that's what the law established. The choice presented to the people in the referendum wasn't "accept this or go back to a dictatorship", as the parent commenter believed. I don't intend to say the politicians involved had an easy job coming up with the appropriate compromises; far from it. But the fact that the support the Constitution got in Catalonia was so overwhelming is definitely not because "it was either that or Franco".
