to get away with (something), to be accepted (unjustly/despite flaws), to go unchallenged

💡 ポイント (Nuance)： Often used in a somewhat critical or exasperated tone, describing a situation where something illogical, unfair, or incorrect is accepted or allowed to happen without proper challenge. It can also mean that something (like an idea or rule) gains widespread acceptance or becomes common practice, sometimes implying it shouldn't. 「そんな理屈が罷り通るのか」「彼の意見がそのまま罷り通った」のように使われる。
