I saw this word from this:
What does it mean?
送官究办 sòng guān jiūbàn - means to be sent to court to be dealt with
送 - to send
官 - means an official building, in this case it means the court
究 - investigate
办 - to be dealt with
Maybe others can provide some insight into whether or not this is still in use
It just means "if someone breaks the rule, he will get punished." Actually, this word is seldom used in China Mainland today. It is more common before 1911.
