The canon reads:
Can. 144 §1 In common error, whether of fact or of law, and in positive and probable doubt, whether of law or of fact, the Church supplies executive power of governance for both the external and the internal forum.
§2 The same norm applies to the faculties mentioned in cann. 883, 966, and 1111 §1.
By the way, on Miss Decker,
CLSA Selects 1999 Scholarship Awardee
The CLSA extends warm congratulations to Ms. Zabrina Decker, recipient of the 1999 Canon Law Society of America scholarship. This year's recipient is a 1988 graduate of Mundelein College, Chicago, with a B.A. in Religious Studies and a 1990 graduate of Loyola University, Chicago, with a master’s degree in Religious Education. Since the fall of 1997, Zabrina has worked full-time as a procurator-advocate in the metropolitan tribunal of the Archdiocese of Milwaukee. She entered the JCL program at the Catholic University of America in Washington, DC, in the summer 1999 semester.
I'm always willing to publicize the good work of our canonists.
