What it means
に照らして means “in comparison with,” “in light of,” or “according to” a standard, rule, principle, fact, or other basis for judgment. It presents the stated noun as the criterion used to evaluate or decide something, and it is especially common in formal, written, and analytical language.
Usage note
に照らして is normally used with an evaluative standard or basis, such as regulations, principles, evidence, or circumstances. It should not be confused with ordinary physical or simple factual comparison, for which 比べて or に比べて is generally more natural.
