Definition and synonyms of three-dimensional from the online English dictionary from Macmillan Publishers Limited.
English (language). In non-legal usage, the expression criminal disposition is just a way of describing someone with a criminal bent of mind. In legal usage, a disposition is the final settlement of matters in a lawsuit and a judge's ruling (such as award of damages, etc). In criminal procedure, the disposition is the sentencing and final settlement of other matters of the criminal case.
With a conviction and sentence imposed, the disposition date is the date of final sentencing even though there is a sentence to be completed (with all the actions attendant to that, like parole hearings, appeals, etc.).
