I’m doing a translation into Latin. I’m having trouble translating the phrase
(something is done) as a matter of principle.
The best I’ve come up with is
praecepti elementarii adseverandi causa.
(Which is a translation of my English re-phrasing of it: “for the sake of asserting a fundamental precept”)
Can anyone suggest something better. I guess there must be an actual equivalent already in Latin lterature. Anyone know what it is?
