Samuelu Sua and his wife Sivai Kepi walked out of the District Court even after being given jail terms, as the time they had already served in remand custody fulfilled their sentence.
Meanwhile, Lise-Marie Schmidt was discharged without a conviction.
Judge Talasa Atoa-Saaga gave her decision on the high-profile conspiracy case on Tuesday.
Prime Minister La'aulialemalietoa Leuatea Schmidt, Li'o Fa'ataumalama Auava and Fepuleai Faimata Su'a were cleared of all charges against them. They were charged along with Sua, Kepi and Schmidt.
The charges stem from Sua claiming to be the eyewitness to the hit-and-run in 2021, which claimed the life of a university student in Vaitele. He claimed that he had seen a politician drive the vehicle that hit the young man.
