Although recognizing that a minority of decisions apply a substantial evidence standard of review on appeal from an order granting or enforcement to a forum selection clause, this decision adopts what it says is the majority rule applying, instead, an abuse of discretion standard of review.  In this case, the contract included not only a clause selecting Illinois as the forum but also a clause choosing Illinois law to govern the contract and its enforcement.  Given the choide of law clause, which the court found no reason not to enforce, Illinois law (which differs slightly from California law) should have been applied to determine whether the choice of an Illinois forum was unreasonable and therefore unenforceable.
