I just read an article in the Austin Chronicle (link) about Fran and Dan Keller, who were convicted of a felony in the Oak Hill satanic ritual abuse trial. The article states that "their felony convictions have been 'vacated', but they're technically on bonded status...the absence of an explicit exoneration leaves her and Dan at the mercy of any online background search."
The article also states that "Their 1992 conviction...has effectively been overturned by a May 2015 Court of Criminal Appeals ruling 'granting relief' to the Kellers...but the ruling was not accompanied by actual exoneration."
I haven't found concrete information online about what effects of the original judgment a vacation or an exoneration reverse, although this statement would imply that a vacation doesn't expunge the criminal record whereas a full exoneration would.
Can these words be precisely defined in terms of what the effects the court can compel to happen? E.g. release from prison, expungment of criminal record, etc.
