A judicial reappraisal brought jointly by the situation groups Greenpeace and Uplift is owed to beryllium heard astatine the Court of Session successful Edinburgh.
The campaigners privation to halt the improvement of Rosebank lipid field, which is disconnected Shetland, and the Jackdaw state field, disconnected Aberdeen. But lipid companies accidental the projects are vital.
If the situation is successful, operators would person to resubmit biology interaction assessments for support earlier drilling tin begin.
It is understood the lipid companies volition judge that the determination to springiness the go-ahead was unlawful - due to the fact that the emissions they would make were not decently assessed - and volition not situation it.
Instead, they are expected to absorption connected however to determination forward, fixed that enactment is already nether way.
What is the judicial reappraisal about?
Consent for drilling successful the Rosebank tract was granted by the regulator, the North Sea Transition Authority (NSTA), successful September past year.
Shell’s proposals to make the Jackdaw tract were approved by the NSTA successful 2022, aft initially being rejected connected biology grounds.
The situation groups accidental that erstwhile consent was granted for the fields, the interaction of emissions caused by burning extracted lipid and state was “unlawfully ignored” by regulators.
Uplift accused regulators of "failing to beryllium transparent" successful granting the consents and said Rosebank would harm marine beingness successful the North Sea.
The UK authorities said successful August that it would not combat immoderate cases implicit Rosebank and Jackdaw.
It efficaciously accepted the archetypal decisions were unlawful.
This came aft the Supreme Court ruled successful June that regulators indispensable see the full biology interaction of caller projects - including the mode fossil fuels are utilized by extremity consumers.
The Supreme Court's determination could inactive beryllium challenged by either side.

Philip Evans, of Greenpeace UK, said: "Earlier this year, the Supreme Court made it crystal wide that the clime interaction of emissions from burning fossil fuels indispensable beryllium assessed earlier immoderate caller lipid and state projects tin beryllium approved.
"It’s these types of emissions that are causing the clime chaos we’re seeing each implicit the world.
"But lipid companies privation to support drilling for maximum profits whilst ignoring the harm they’re doing.

Tessa Khan, enforcement manager of Uplift, said Rosebank should ne'er person been approved.
She said: "Rosebank is simply a unspeakable woody for Britain. It’s mostly lipid for export, which would bash thing to little substance costs oregon boost our vigor information yet, due to the fact that of immense taxation breaks for caller drilling, the UK nationalist would efficaciously screen astir each of the costs of processing it portion the lipid companies locomotion disconnected with the profits.
"It won’t supply semipermanent information for lipid and state workers either.
"Even with caller fields being approved, jobs supported by the manufacture person much than halved successful the past decade. Workers request clean-energy jobs that person a semipermanent future."
Lord Deben, erstwhile president of the authorities watchdog the Climate Change Committee, said: "Rosebank and Jackdaw should ne'er person been approved by the erstwhile government.

What bash the lipid companies say?
Norwegian vigor elephantine Equinor and British steadfast Ithaca Energy jointly ain the Rosebank field.
They person said it would make astir 1,600 jobs during its operation and enactment astir 450 UK-based jobs during its lifetime.

"Stopping the enactment is simply a highly analyzable process, with important method and operational issues present that infrastructure is successful spot and drilling has started successful the North Sea.
"Jackdaw volition supply capable substance to vigor 1.4m UK homes arsenic older state fields scope the extremity of production."
The UK authorities has antecedently pledged that lipid and state would play an important relation successful the system "for decades to come" arsenic the UK transitions to cleanable energy.
The Scottish authorities has antecedently said it had a "presumption against" caller lipid and state exploration.
However, First Minister John Swinney said successful June that it would inactive beryllium needed "for a play of time" to assistance the state conscionable its net-zero targets by 2045.
