Plain-English Summary
Section 3-110 sets the outer shape of judicial review: every action to review a final administrative decision is heard and determined with all convenient speed, and the hearing and determination extend to all questions of law and fact presented by the entire record before the court.
The court doesn't build a new evidentiary record. No new or additional evidence in support of, or in opposition to, any finding, order, determination, or decision of the agency is heard by the court — review runs on what the agency already developed.
On questions of fact, the agency's findings and conclusions are held to be prima facie true and correct. The section doesn't itself spell out the mechanism for challenging that presumption beyond what the entire record shows; it fixes the presumption as the starting point for the court's review of the facts.
Frequently Asked Questions
Can I introduce new evidence during judicial review of an agency decision?
No. Section 3-110 says no new or additional evidence in support of or in opposition to the agency's finding, order, determination, or decision is heard by the court.
What record does the reviewing court look at?
The entire record before the court from the agency proceeding; the hearing and determination extend to all questions of law and fact presented by that record.
How does the court treat the agency's factual findings?
As prima facie true and correct.
Does the court reweigh both legal and factual questions?
The hearing and determination extend to all questions of law and fact presented by the entire record, though the agency's findings on fact questions carry the prima facie true and correct presumption.
Is there a time standard for how quickly the court must decide the review action?
Yes. The section requires that the action be heard and determined with all convenient speed.
