Apples to Oranges?  No.  In each case, a controversy was put to rest by the Pope's saying, "Rome has spoken. Case closed."  The particulars of the cases don't are irrelevant, because Francis saying that "once Rome has spoken, that's it" was not tied to any particular issue, but stated as a rule.  You and I may or may not like that rule, but Francis did state it as a rule, as did JPII.
