Rebekah Shaman, a local campaigner, successfully challenged Lambeth Council in the High Court, leading to the cancellation of upcoming festivals, including Mighty Hoopla, at Brockwell Park due to lack of planning permission. The court ruled that the park’s use for events exceeded the allowable 28 days without additional consent, prompting Shaman’s group to request the council confirm the cancellation and remove any event-related infrastructure. The decision was celebrated by campaigners and notable figures like Sir Mark Rylance, emphasizing the need to protect the park’s ecological integrity from large-scale commercial events.
