A certain pro-guilt commentator thinks he has sorted out the issue around Stefanoni's qualifications. He has not.
Here's the truth:
It's true that in 2001/2002, the Italian university qualifications system changed. In essence, it changed the old-style "diploma" degree into " 3-year laurea" ("L3"). This qualification is now equivalent to an undergraduate degree (BA, BSc, BEng).
The old-style laurea degree was, at the same time, reclassified as "laurea specialistica" ("LS").
And beyond that, nothing really changed. Before and after the reforms, anything above the laurea degree was termed "post-laurea" (equivalent to "post-graduate"), and consists of specialist dottorato di ricerca (doctor of research) qualifications and the like.
Here's a comprehensive description of the pre- and post-2001/02 situation:

So, here's the truth: Stefanoni gained an old-style laurea qualification. This was equivalent to an enhanced post-2001/02 laurea specificata degree. But Stefanoni NEVER gained anything related to post-laurea qualifications. She cannot, therefore, be considered the equivalent of a PhD. End of story.
Oh and by the way, another interesting fact: it appears that the L3 degree (i.e. the modern equivalent of an undergraduate first degree) is awarded to students who have obtained 180 credits:
The Laurea-L (first degree) is awarded to undergraduates who have obtained 180 credits
And I seem to remember reading somewhere recently that Stefanoni graduated with 180 credits. If that's correct, then Stefanoni would indeed simply hold the equivalent of an undergraduate first degree (it appears that 300 credits in total are required for a laurea magistrale). But anyhow, even under the most optimistic assessment, the most that Stefanoni holds is the rough equivalent of a masters degree. She categorically does not hold the equivalent of a PhD. And, as such, she categorically is not entitled to style herself "Doctor" outside of Italy.
