Shale explorer Cuadrilla has applied for an injunction forbidding trespassing at its Preston New Road site in Lancashire.
Cuadrilla today submitted the papers to the High Court in preparation for a hearing on May 31.
The injunction would also prohibit unlawful obstruction of the site entrance and adjacent main “A” road.
Cuadrilla chief executive Francis Egan said: “Whilst we fully respect the right to peaceful and legal protest, unfortunately over the last 18 months we have seen an extraordinarily high level of unlawful protest activity.
“This has been directed at and impacted not just our workers but also our suppliers and other law abiding citizens using the main road passing our site for their normal daily activities.
“Such unlawful conduct cannot be permitted to continue, and we hope that if we can secure this injunction it will deter this unlawful behaviour which is reckless and continues to cost local taxpayers millions of pounds.”
The hearing is scheduled to take place at Manchester High Court District Registry.
