Questions & Answers about С точки зрения закона он прав.
Why is the word закон in the Genitive case (закона)?
It is required by the phrase с точки зрения (from the point of view of). Just like in English where you say "of the law," in Russian this relationship is expressed using the Genitive case. This is a highly useful phrase for attributing views or perspectives in formal and semi-formal speech.
Why do we use the short-form adjective прав here instead of the long form правый?
When expressing that a person is "correct" or "right" about a situation, Russian uses the short forms: прав, права, право, or правы. The long form правый is mainly used for the physical direction "right" (as in the right side) or political leaning.
Should there be a comma after с точки зрения закона?
Unlike many other introductory or reporting phrases (like по-моему or к счастью), phrases starting with с точки зрения do not usually require a comma unless you are deliberately pausing for strong emphasis. It generally flows as a standard adverbial modifier rather than a detached introductory phrase.
How does this compare to saying по закону?
Both mean that legally, he is in the right. По закону translates closer to "by law" or "according to the law" and is slightly punchier. С точки зрения закона is a bit more analytical, literally setting up the "legal perspective" as the frame of reference, which fits perfectly when weighing different viewpoints.
