Man. Post. Cap. IX: GAR 5 — singular act enters by reatus, not substance
nd so although a singular action, by reason of its substance, cannot be said to enter into another, yet by reason of guiltt is rightly said to enter, insofar as because of that action another is held guilty, and so lies under penalties.
Latin
GAR. 5. Itaque quamquam singularis actio, ratione substantiae suae non potest dici introire in alium, tamen ratione reatus introire recte dicitur, quatenus propter actionem illam alius reus habetur, adeoque poenis subiacet.
