Otavini (sic) had a farm, ee-aye-ee-aye-oh,
And on that farm he had a cow, ee-aye-ee-aye-oh.
With a moo-moo here and a moo-moo there,
Here a moo, there a moo, everywhere a moo-moo.

All popes since Pius XI have upheld the teaching contained in his Encyclical, Casti Connubii or as you term it Consorto Cunnubii (sic). An easy and forgivable mistake to make save for the spelling 'Cunnubii' which might suggest another etymological root.
Cardinal Ottaviani undoubtably did play a part in the promulgation of Humanæ Vitæ. As Pro-Prefect of the Holy Office he was bound in duty and conscience before God to prevent the Pope from putting his name to an heretical document. 
Ottaviani's intervention amongst that of others, did not put papal authority in jeapordy (sic). That authority was virtually destroyed by the cowardice of bishops and clergy worldwide who failed to back the Pope, the Holy Office, Scripture and the Tradition of Christ's  Church.
