Ury & Wiggins (1971) have used the Bonferroni inequality to obtain shorter confidence intervals for multiple comparisons among means, for most situations of interest, than those proposed by Marascuilo (1966). Their attempt to extend this technique to contrasts chosen post hoc has been shown to be not generally valid by Rodger (1973). A valid extension is given here.
