California court decision strengthens Coastal Commission authority over disputed pipeline project

The big legal fight over California oil

A California appeals court just made a major decision about offshore oil drilling. The court sided with state regulators who want to block repairs on a key pipeline system along the Santa Barbara coast.

This legal fight involves Sable Offshore Corp., a Houston-based company. They bought the pipeline system in 2024 and wanted to restart oil production. But the California Coastal Commission said no, and now the court agrees with them.

The court says the Coastal Commission has the power

The California Second District Court of Appeals ruled that the Coastal Commission was acting within its authority. The commission issued cease-and-desist orders against Sable’s pipeline work, and the court backed them up.

This means state regulators can block repairs on the CA-324 and CA-325 pipelines. These lines connect offshore oil platforms to refineries. The court decided the commission didn’t overstep its legal boundaries when it stopped the work.

Old permits vs new work

The dispute goes back to 1986, when Santa Barbara County issued coastal development permits for the pipeline system. Sable argued that those permits allowed its repair and maintenance work without new Coastal Act approval.

The Coastal Commission disagreed and issued enforcement orders after Sable continued work. The appeals court did not decide every permit issue; it ruled that the commission had authority to enforce its order after the county declined to act.

The 2015 oil spill that changed everything

One of these pipelines, CA-324, caused a huge disaster in 2015. It ruptured and spilled over 100,000 gallons of crude oil into the Pacific Ocean near Refugio State Beach.

The spill killed hundreds of birds and marine mammals. It also blackened miles of coastline. The company that owned it at the time, Plains All American Pipeline, was convicted of felony charges and paid millions in fines.

Fun fact: Over 100,000 gallons of crude oil from the 2015 spill were never recovered.

Sable’s big purchase and big plans

Sable Offshore acquired the Santa Ynez Unit assets from ExxonMobil in February 2024. The pipeline and offshore platforms had been shut down since the 2015 Refugio oil spill while regulators, courts, and the company fought over what approvals were needed before a restart.

Sable planned to resume production from the Santa Ynez Unit by repairing the Las Flores pipelines and adding safety upgrades. The company argued the 1986 permits allowed that work without a new Coastal Act approval.

Fun fact: Sable’s CEO, Jim Flores, said the company is providing American oil from American soil through an American pipeline to an American refinery.

The Coastal Commission says not so fast

When the California Coastal Commission learned about Sable’s work, they weren’t happy. In November 2024, they issued a cease-and-desist order stopping the construction.

Then in February 2025, they issued another order. The commission even fined Sable $18 million for continuing its work without permission. The state agency made it clear that you need our approval for this kind of project, no matter what the old permits say.

Sable fights back in court

Sable challenged the commission’s actions in Santa Barbara County Superior Court. The company argued they hadn’t received proper due process during the hearings.

They also claimed the commission had no authority because the county had already said the work was okay. But the appeals court rejected both arguments, saying Sable got a full and fair opportunity to present their case.

The county got caught in the middle

Santa Barbara County found itself stuck between Sable and the Coastal Commission. The county initially told Sable that its repair work was authorized by existing permits.

But the county also told the commission they hadn’t actually approved anything. This confusing situation helped Sable argue they were in the right. However, the appeals court saw it differently and sided with the state regulators.

Then the federal government stepped In

By March 2026, the Trump administration was citing fuel-supply risks tied to the Iran conflict. Energy Secretary Chris Wright directed Sable to restore the Santa Ynez Unit and pipeline system under Defense Production Act authority.

The Energy Department said the restart was needed to strengthen oil supply and support West Coast military readiness. Sable began shipping hydrocarbons through the pipeline in March, even as California officials said the move conflicted with state court orders and state oversight.

Oil is flowing despite court orders

Sable says oil is moving again through the pipeline after the March 2026 federal order. The company announced that it resumed hydrocarbon transportation on March 14 and began oil sales later that month.

Sable has argued in state litigation that earlier permits allowed its repair work, while the federal government separately relied on Defense Production Act authority to order operations restored. California officials still say the restart violates state law and prior court orders, so the dispute remains active.

What did the appeals court actually rule?

On June 17, 2026, the appeals court upheld the preliminary injunction against Sable. Two of the three justices agreed that the Coastal Commission had authority to issue and enforce its cease-and-desist order after Santa Barbara County declined to act.

The dissenting justice argued the repair work was already done and oil was flowing after federal intervention. The majority still found the appeal was not moot because the preliminary injunction remained in effect.

More legal fights are coming

This court decision doesn’t end the battle. Additional lawsuits are still pending, including one from California State Parks trying to stop Sable from using the pipeline under Gaviota State Park.

A federal judge recently denied that request, saying the parks department didn’t prove they’d suffer irreparable harm. So the legal fights continue on multiple fronts, with both sides digging in for a long struggle.

What does this mean for California and you?

This whole situation shows how complicated energy policy has become. The state wants to enforce environmental laws and prevent another oil spill disaster.

But the federal government says we need domestic oil production for national security. Meanwhile, gas prices are high, and everybody feels the pinch at the pump. The court’s ruling gives the state some power, but the oil keeps flowing anyway.
