Those who break the law will be punished.
Literal
Law [object-を] broke one-[もの] [topic-は] be-punished-[passive-される]
ここでは 法 (the formal/literary short form) is used for the law, and 破る ('to break') for the violation. 破る is the natural verb for promises, rules, laws, records, silence — abstract things that 'break,' as opposed to 犯す for committing a violation. もの here is written in hiragana, still referring to a person generically.
