People Ex Rel. Madigan v. Illinois Commerce Com'n
964 N.E.2d 510
Ill. App. Ct.2011Background
- IAWC sought rate increases; AG appealed challenging recovery of unamortized prior rate-case expense and adequacy of 9-229 fee findings; IAWC cross-appealed about Service Company fees; Commission approved rates increasing revenue by $42 million; prior rate-case expense and its amortization were included in the test-year calculations; Court reviewed deference standards and ratemaking principles; remand only on 9-229 findings.
- The test-year framework used a future 2010 test year; Illinois Administrative Code 287.20 governs test-year timing; amortization of prior rate-case expense has long been approved in past practice; the Commission included the unrecovered $657,530 in the current rate case amortization.
- The Commission’s order analyzed but did not fully explain the basis for attorney/expert-fee justness and reasonableness under 9-229; the Service Company study mandate from prior docket was not followed with appropriate detail; public comments were considered but not treated as evidence.
- Multiple studies (Service Company Cost Study, Self-Provision Study, Belleville lab study) supported cost comparisons but the Commission found they did not meet the prior docket’s directive; the Commission capped Service Company fees at 5% over the prior order.
- Cross-appeal jurisdiction was addressed under Rule 335 and Rule 303(a)(3); the court held cross-appeal timely and within its jurisdiction.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether unamortized prior rate case expense can be included in a new rate case. | Madigan argues test-year rule violation and retroactive/single-issue ratemaking. | IAWC/Commission defend traditional amortization and practice. | Not a test-year violation; not retroactive or single-issue. |
| Whether the Commission complied with 9-229 on attorney/expert fees. | Madigan contends insufficient explicit basis for fees under 9-229. | Commission relied on staff data and overall reasonableness. | Remanded for additional 9-229 findings. |
| Whether Service Company fees were properly determined. | IAWC argues full evidence supports higher fees. | Commission lacked compliant data per prior order; capped at 5% above prior amount. | Affirmed cap and fee denial; Service Company fees upheld at lower level. |
| Whether cross-appeal jurisdiction and timeliness were proper. | IAWC asserts Rule 303(a)(3) allows cross-appeal; timely. | Commission argues no direct-cross-appeal deadline in statute. | Cross-appeal timely under Rule 303(a)(3); jurisdiction proper. |
