In 1991, the Minnesota Legislature required utilities to pay for environmental costs as a component of the price paid for the purchase of energy.
The Minnesota Legislature directed the Minnesota Public Utilities Commission to determine environmental cost values for each method of electricity generation and required utilities to use those values in proceedings before the commission. The commission set interim environmental cost values for five air pollutants on March 1, 1994, including carbon dioxide (CO2). The commission also initiated a contested case proceeding to set final environmental cost values. On January 3, 1997, the commission set final values for six air pollutants.
The relators filed a certiorari appeal alleging that the commission’s decision to set values for CO2 was improper.
The court had to analyze the following two questions:
1. Is the commission’s order ripe for consideration?
2. Did the commission act improperly in determining CO2 values?
Regarding the first question the court found that, inter alia, because the commission’s order was a final order, and because the statute clearly required the commission to use the values in some manner, the relators could suffer hardship if the court did not review their challenges to the commission’s order setting CO2 environmental cost values. The commission’s order was therefore ripe for consideration.
Regarding the second question, the court held that substantial judicial deference had to be accorded to the fact finding processes of an administrative agency. An agency’s expertise was entitled to deference from reviewing courts, and the agency’s decision was presumed correct. Here, the legislature assigned the task of determining environmental cost values to the administrative agency it presumably thought would be most appropriate to take on this responsibility. Thus, the court would not substitute its judgment for the commission’s in such a situation.
The relators argued that the speculative nature of the evidence on which the commission relied in setting the CO2 values showed that commission’s decision was not supported by the record. The court held that the commission conducted a careful review of (1) Intergovernmental Panel on Climate Change (IPCC) research and the peer review process; (2) research on CO2 values by other scientific review panels; (3) the uncertainties in the scientific reports and how the uncertainties were acknowledged in the scientific community, among others. It also based its decision on the testimony of expert witnesses. Under these circumstances, the commission had based its decision on sufficient evidence in the record.
The commission had acted pursuant to a valid delegation of authority from the legislature in an area in which the courts were not accustomed to dealing. Accordingly, the court concluded that the commission’s determination that CO2 negatively affected the environment was proper.
While it acknowledged the concerns about the uncertain and speculative nature of the available data, it was disinclined to prohibit the state from directing its instrumentalities to engage in environmentally-conscious planning strategies. Thus, the commission’s order concerning CO2 environmental costs was supported by substantial evidence, not contrary to legislative intent, and was not contrary to law.
