A campaigner won a high court challenge for using South London Park for the festival this summer.

Lambeth Council allows a series of events in Brockwell Park near Herne Hill, such as the mighty The Mighty Hoopla, which is expected to attract thousands of people.

Local resident Rebekah Shaman took legal action, deeming the council not having the right plan permit - the judge was in her favor.

A Lambes Council spokesman said: “We are currently evaluating the impact of this judgment and determining the next step.”

The shaman's argument revolves around planning laws that prohibit the use of the park from being used for more than 28 days a year without the consent of other plans.

In charge of the case, Justice Moore found that some of the activities in the park will be used for these activities for up to 37 days.

The judge said his ruling was merely about the legitimacy of the extra approval of the Council's decision - a decision he called "irrational".

Ms. Shaman told BBC London: "We are very happy, it's been a long time. Unfortunately, we had to put Lambes Parliament in court; it's not what we want to do, but we feel they are not interacting with us.

“It has been happening for years, it’s not a one-off situation, it’s been so deteriorating at the park that the community must speak out to protect the future generations of the park.”

“We hope to reach an agreement and the incident can still continue, but at a lower level and have more connections with the community,” she added.

Lawyers for Lambes Council and Festival Organizer Summer Events Ltd. asked for permission to challenge his decision, but the judge refused.

However, they are still able to ask the Court of Appeal to allow the decision to be challenged directly.

Actor Mark Rylance, who supported the campaign’s Oscar winner, called the ruling “good news.”

"I think the result is great. I've been to a festival for many years, but the subsequent damage to the park was very bad...I'm totally very happy."

Matt, who has lived in the area for the past 12 years, said: "I'm really happy with the results because it's a victory for the local community that has been fighting the Lambeth Council for a long time."

But local resident Lucy told BBC London: “I think it’s a great thing to bring the festival to Brockwell Park, and I think it’s a great cultural celebration and we need to provide opportunities for young people and we need to keep the art alive.”

Richard Harwood KC told Shaman that Brockwell Park has been used in large-scale commercial events in recent years, in which a “large amount” of the park was surrounded by the public, causing damage to the ground.

Mr Harwood added: “The park effectively turned muddy due to the weekend weather of a commercial event.”

Matthew Reed KC of Lambeth Council said the "majority" of the park is still not spread and is available for public use during the event.

He also said the council was able to legally decide how often the park was used for festivals and obtain special permission if needed.

But Judge Moore found in the ruling that the planning officers of Lambes Parliament “made mistakenly consider the prospect of granting the plan’s permission”.

Brockwell Park Group has previously stated that it is not an "anti-hunter" and supports "well-run inclusive activities."

"These large-scale, high-impact business festivals are undermining the ecological, heritage and community value of Brockwell Park," the organization said in a statement.

“The park is overused and underprotected.”
