Tyler and Rasinski (1991) challenge Gibson's (1989) contention that pe
rceptions of procedural justice do not influence citizens' compliance
with unpopular Supreme Court rulings. Noting a significant correlation
between procedural justice and institutional legitimacy, Tyler and Ra
sinski argue that perceptions of procedural justice exert indirect inf
luence on compliance. In response, Gibson (1991) questions Tyler and R
asinski's interpretation of the causal relationship linking institutio
nal legitimacy and perceptions of procedural justice. Although both si
des in this dispute offer persuasive discussion, neither can advance c
onclusive empirical evidence regarding the question of causality. This
note presents a reexamination of the relationship between institution
al legitimacy and procedural justice, with data drawn from an experime
nt designed specifically to address the question of causality. Results
do not enable conclusive assessment of the Gibson hypothesis. However
, in contrast to the Tyler-Rasinski hypothesis, no evidence is found s
upporting the contention that perceptions of procedural justice influe
nce perceptions of institutional legitimacy.
