This publication is a modified version of a paper prepared in 1971 for the Public and Administrative Law Reform Committee, concerning the desirability of enacting a code of procedure for administrative tribunals. On the one hand, such a code would firmly establish principles of fairness and remove existing uncertainties. On the other, the functions and characteristics of tribunals are so various that a single code would either be a Procrustean bed or would be so flexible as to be useless. In this paper, in an effort to get beyond and to develop these generalities, Kenneth Keith considers first the differences between tribunals and certain other factors which cast doubt on the desirability of having a comprehensive, binding code which is not hopelessly vague. Secondly, a discussion of the procedures required by legislatures and courts perhaps redresses the balance by showing that many rules do in fact frequently recur. To conclude the author sums up the possible outcomes.
