an authoritative opinion.
Let us assume this case has been handed down in a legal system that treats the decisions of its highest court as authoritative precedents.
Pleasingly, the book's written style is clear and authoritative.
Precedents cannot be normatively authoritative for any behavior.
All they need to resolve their dispute is the arbitrator's decision-appealing to the plaintiff's rule as an authoritative rule makes no additional difference to them.
By contrast, the precepts of custom emerge and develop gradually instead of being brought into existence through discrete and authoritative acts.
Likewise, those laws and rules are subject to deliberate alteration through standard procedures undertaken by the people in the authoritative positions.
Neither theoretical pronouncements not practical directives have to be exclusionar y if they are to be, or be treated as being, authoritative.
We might add executive authority to account for authoritative figures like police officers and tax officials.
