Heathrow Airport Ltd v Persons Unknown

[2024] EWHC 2599 (KB)
Heathrow Airport got a court order to stop environmental protestors from disrupting the airport. The judge said there was a serious risk of people getting hurt and the airport losing lots of money if the protests went ahead, so the injunction was needed to protect people and the airport's operations.

Key Facts

  • Heathrow Airport Limited sought a precautionary injunction against Persons Unknown planning environmental protests.
  • The planned protests involved actions like cutting fences, gluing to runways, and disrupting airport operations.
  • Just Stop Oil (JSO) and similar groups were identified as potential perpetrators.
  • The Airport is a designated Critical National Infrastructure site, and the protests posed risks of serious harm, financial losses, and significant public inconvenience.
  • The application was made without notice to the defendants due to concerns about the risk of irreparable harm if notice was given.
  • The injunction covered a specified area of the airport shown on provided plans.

Consideration of byelaws as a means of control.

Wolverhampton Travellers, [216]-[217]

Outcomes

The court granted the precautionary injunction.

The court found a real and imminent risk of serious harm, including injury and death, substantial financial loss, and significant public disruption. The court determined that the defendants had no legitimate right to trespass on the airport and that the balance of convenience strongly favoured granting the injunction. The existence of byelaws was deemed insufficient to prevent the anticipated disruption.
