Good thinking, monica!  Rat's dissertation came on the heels of a post-Vatican II  innovation called the American Procedural Norms, which were approved by the Vatican and instituted in USA matrimonial tribunals.  In a somewhat parallel development, American tribunals developed a practical jurisprudence, including "psychological impediments (scizophrenia, PTSD and many more) which like the APN, were intended to speed cases through Tribunals to accommodate need.  For some time, American tribunals were producing more annulments than the reso of the world's, combined!  Of course the Vatican Curia was aghast, and JP II "was not amused," but the case flow has continued, with cautions.  And you're right -- the WHOLE business IS Byzantine, even though it may look good and sound nice.  Furthermore, it's so Byzantine, even with the latest reforms, that the system is unworkable.  And THANK YOU for your insights!
