London resident Karen Imber faced legal action after claiming her flood-affected home was unsellable during mediation. Claiming damages from sewage flooding, she settled for £225,000. However, unbeknownst to the mediators, Imber had already sold the property for £780,000 prior. Thames Water uncovered the sale, leading to a court ruling that required her to return the settlement funds, highlighting issues of fraudulent misrepresentation.
