Ill. Sup. Ct. R. 20
This rule permits the Supreme Court of the United States or the United States Court of Appeals for the Seventh Circuit to certify a question of Illinois law to the Supreme Court of Illinois, which question may be controlling in an action pending before said court and upon which no controlling Illinois authority exists.
The Court of Appeals for the Seventh Circuit has a rule which encourages certification in jurisdictions that have a rule similar to the one provided herein. See Rule 13 of the Rules of the United States Court of Appeals for the Seventh Circuit.
Subparagraph (a) establishes the standard for certification and also makes the acceptance of certification by the Supreme Court of Illinois discretionary.
Subparagraph (b) establishes the contents of a certification order.
Subparagraph (c) provides that the Supreme Court of Illinois may require the original or copies of all or any portions of the record before the certifying court.
Subparagraph (d) provides that briefs and arguments are to be governed by the Supreme Court of Illinois rules dealing with briefs and oral arguments. Amended in 1992 to provide that the time schedule for briefs will not begin to run until the court decides that it will answer the certified question.
Subparagraph (e) of the rule provides for fees and costs in the Supreme Court of Illinois.
