JACK KNOPFER et al. , Plaintiffs and Appellants, v. HOUSTON I. FLOURNOY, as State Controller, et al. , Defendants and Respondents (Opinion by Friedman, J. , with Richardson, P. J. , and Janes, J. , concurring. ). . . ' In this mandate action appellants complain that the State Controller is making unauthorized deductions from the payments directed by section 4800. This cryptic allegation is the only hint in the record or briefs that income tax withholding may be involved. Federal and state tax agencies are not parties to this litigation and questions of taxability have not been briefed. We do not decide whether the payments in question are subject to federal or state income taxation or income tax withholding.
