Disinterested; treating all alike; unbiased; equitable; fair.

“The language of the provision of the Bill of Rights is that the accused, ‘shall have a fair trial by an impartial jury.’ ‘Impartial’ means ‘not partial; not favoring one party more than another, unprejudiced, disinterested, equitable, just.’  To be impartial means the party, his cause or the issues involved in his cause, should not-must not-be prejudged. The accused is entitled to a fair trial by an impartial jury, and there is no other method provided by which he can be tried and punished.”  Duncan v. State, 79 Tex. Crm. 206 (1916).
