No, states are not obligated to follow other states legal decisions; however, the decisions may carry persuasive weight with the court, assuming (for example) the Iowa Supreme Court ruling doesn't violate the Illinois state constitution or statutes.If Iowa is is the only other state court system that has addressed this PARTICULAR issue then the decision of Iowa's Supreme Court can be used as "precedent" for the Illinois court to follow. If there are other states that have addressed this PARTICULAR issue and they have either agreed with, or disagreed with, the Iowa court's findings, those decisions should be also be taken into account when the Illinois court considers the issue.
