What does the legal term sustained mean?

Answer 1

Sustain is a term that is subject to several definitions.

In the context of trial practice, it refers to a judge agreeing that an attorney's objection is valid.

(e.g.: If an attorney asks a witness a question, and the opposing lawyer objects, saying the question is legally "improper" or some other objection, if the judge sustains the objection, the question cannot be answered nor asked again.)

In the context of appellate practice, an appelate court sustains a lower court judgment, if it leaves it intact, rather than overrules it.
