Justice Antonin Scalia left an indelible mark on American law. His prodigious intellect, distinctive style, and sharp wit will be sorely missed by his family, friends, and colleagues.

Suddenly the Supreme Court has become a huge prize in the 2016 elections.

His passing also creates a once-in-a-lifetime opportunity to shift the balance of power on the Supreme Court toward greater protection for the environment and greater access to the courts by those most affected by pollution and resource degradation.

A look at Scalia’s legacy reveals why his absence in the coming months could be a pivotal factor on environmental issues.

With few exceptions, such as his opinion in Whitman v. American Trucking upholding the Environmental Protection Agency’s authority to set and his opinion in City of Chicago v. EDF rejecting industry arguments that , Justice Scalia’s environmental legacy is decidedly negative.

Interpreting “standing” and “harm”

He consistently voted in favor of property rights over protection of endangered species, wetlands, and other natural resources. He dissented in the court’s landmark ruling in that the Clean Air Act authorizes the agency to regulate the carbon pollution causing global warming and ocean acidification.

He wrote the in a case limiting the EPA’s authority to require preconstruction permits for new power plants that emit only greenhouse gases. He wrote overturning the mercury rule on a technicality—namely, that the EPA should have considered cost as a threshold matter before even embarking on the rulemaking instead of at the stage when the regulations were actually being applied to specific facilities.

His passing also creates a once-in-a-lifetime opportunity to shift the balance of power on the Supreme Court.

He argued that the should be to apply only to “relatively permanent bodies of water” rather than, as the lower courts had consistently ruled for more than 30 years, to the entire tributary systems of the nation’s major waterways.

His passing also creates a once-in-a-lifetime opportunity to shift the balance of power on the Supreme Court.

And he was the author of several decisions severely limiting the ability of environmental plaintiffs to challenge unlawful government actions. This includes, which the late Justice Blackmun characterized in his as a “slash and burn expedition through the law of environmental standing.”

To establish standing, a plaintiff must show how it is injured by the action being challenged. Scalia applied a more liberal test of injury for industry plaintiffs than for environmental plaintiffs. Standing was presumed whenever industry alleged that a government action might cause undue economic harm but not when an environmental organization alleged that the same action would cause undue environmental harm.

Whither the Clean Power Plan?

Though President Obama has said he intends to nominate a successor “in due course,” Senate Republicans have vowed to stall the confirmation process in the hope that they will win the White House and have the opportunity to nominate someone more to their liking.

Suddenly the Supreme Court has become a huge prize in the 2016 elections. Given the stakes involved, it is likely that the vacancy will remain well into 2017, and the court will be forced to make a number of difficult decisions with an evenly divided bench.

Justice Scalia’s environmental legacy is decidedly negative.

A split court has important implications in a number of key environmental cases.

Top of the list is the president’s Clean Power Plan (CPP), a rule that requires states to develop plans to lower carbon dioxide emissions from power plants. Only days before Scalia’s death, the court in a 5-4 party-line vote the rule’s implementation pending a decision by the D.C. Circuit, which has scheduled oral argument for June 2. The stay order provides that it will remain in effect until the Supreme Court either denies review (unlikely) or issues a .

Most observers believe the government, arguing that the Clean Power Plan is legal, drew a favorable panel on the D.C. Circuit court, which includes Judge Sri Srinivasan, who is rumored to be on Obama’s short list of nominees for Scalia’s seat.

Assuming Srinivasan remains on the panel, and further assuming the panel issues a decision this year upholding the CPP (not a foregone conclusion), there is a good chance the vacancy on the Supreme Court will not be filled by the time the case arrives there in 2017. This increases the odds of a 4-4 split, which would result in the DC Circuit decision being upheld, and the CPP dodging a bullet.

Clean Waters Act at court

Another case that may be affected by Scalia’s departure but with far less at stake is .

The question presented is whether landowners can go to court immediately when regulators make what is called a “jurisdictional determination” under the Clean Water Act finding, for example, that there are wetlands on the property that may require a permit to fill.

There is a clear conflict in the circuits on this question. The Eighth Circuit, in Hawkes, held that jurisdictional determinations were reviewable in court, whereas the Fifth Circuit in ruled that they are not.

Interestingly enough, the disagreement rests on how to read Justice Scalia’s opinion in . In that case, a compliance order under the Clean Water Act required restoration of an allegedly illegally filled wetland and exposed the recipient to potential penalties of $75,000 per day. Scalia ruled that the compliance order in that case was a “final agency action” for which there is no adequate remedy in a court other than judicial review under the .

Justice Kennedy wrote a concurring opinion rejecting Scalia’s approach …

Another case being closely watched is the challenge to the EPA’s Clean Water Rule that seeks to “clarify” the and whether it covers tributaries that feed into waters protected by the act.

The need for clarification stems in large part from the Supreme Court’s decision in , where the court split 4-1-4 and Justice Scalia authored a plurality opinion that would significantly reduce the scope of the act.

Justice Kennedy wrote a concurring opinion rejecting Scalia’s approach and establishing a “significant nexus” test—requiring the government to prove that a wetland, alone or in combination with other wetlands in the watershed, plays an important role in protecting the quality of the water downstream and therefore is subject to the Clean Water Act. Because Kennedy’s significant nexus test has been adopted by nine circuit courts as the controlling opinion from Rapanos, the EPA used it as the basis for the Clean Water Rule.

The Sixth Circuit has stayed the rule pending its decision on whether it has exclusive authority to decide its legality. If the Sixth Circuit asserts jurisdiction, a final decision could be issued this year and the Supreme Court would then be faced with another petition for review, knowing that it could result in yet another divided decision.

Finally there is a case involving the cleanup of Chesapeake Bay, which is heavily polluted by agricultural runoff and other sources. The Third Circuit upheld the EPA’s landmark cleanup plan in a case brought by the American Farm Bureau and .

The issue presented is whether the EPA exceeded its authority by developing a complex “pollution budget” and allocating responsibility for reducing the inputs of nitrogen and phosphorous throughout the eight states that comprise the basin. Whether to grant review will be considered at the next conference which is scheduled for February 26. This will be the first test to see whether the post-Scalia court has the appetite to take up a case where there could be a 4-4 split.

With these and other environmental issues on the docket, the absence of Scalia will have a huge impact—as will the question of his eventual successor.
