close attention of legal commentators.11 In the case at bar, however, no claim is made that the master list, or indeed the venire drawn therefrom, was unrepresentative.
Secondly, a number of prospective jurors thus selected are disqualified or excused by judges or various court personnel on grounds of competency (Code Civ. Proc., §§ 198, 199), suitability (id., §§ 204d, 205, subd. (a)), undue hardship (id., § 200), or, until recently, occupation (id., former § 200, repealed by Stats. 1975, ch. 593, § 2, p. 1310). The almost total elimination in 1975 of automatic exemptions for occupational reasons was a commendable step towards preserving the representative character of the jury.12 But the continuing power to excuse prospective jurors on the grounds of “suitability” and “undue” hardship is highly discretionary in nature, and courts must be alert to prevent its abuse. In particular, excessive excuses on such grounds as sex, age, job obligations, or inadequate jury fees, can upset the demographic balance of the venire in essential respects.13 Again, defendants herein do not complain of such abuse.
Thirdly, when the case is called for trial the clerk draws the names of veniremen at random from the “trial jury box” (Code Civ. Proc., § 600), and the parties may exercise their statutory challenges to the jurors thus chosen. (Pen. Code, §§ 1055-1089.) Challenges to an individual juror are of two kinds, peremptory and for cause. (Id., § 1067.) A peremptory challenge is “an objection to a juror for which no reason need'be given, but upon which the Court must exclude him.” (Id., § 1069.) A challenge for cause is either “general”—the juror is legally incompetent to serve in any case—or “particular”—-the juror is actually or impliedly biased in the specific matter on trial. (Id., §§ 1071 -1073.) Actual bias is ‘ ‘the existence of a state of mind on the part of the juror in reference to the case, or to either of the parties, which will prevent him from acting with entire
