The Muggle-Worthy Excuse Committee is a division within the Ministry of Magic tasked with a critical component of maintaining the secrecy of the wizarding world. Its primary function is to invent and disseminate plausible, non-magical explanations for incidents of magic that have been witnessed by Muggles. When a breach of the International Statute of Secrecy occurs, the Committee works in conjunction with other divisions of the Department of Magical Accidents and Catastrophes, such as the Accidental Magic Reversal Squad and the Obliviators. While Obliviators may erase or modify the memories of Muggle witnesses directly, the Committee's work provides a necessary cover story for any lingering evidence or widespread public awareness that cannot be entirely contained by Memory Charms. Their excuses are designed to be mundane and believable enough for the non-magical community to accept, preventing panic or suspicion.
The Committee's work is mentioned on a few occasions, typically in relation to major magical disturbances.
The Muggle-Worthy Excuse Committee serves as a key world-building element, illustrating the bureaucratic and logistical challenges of concealing an entire magical society from the non-magical world. Its existence demonstrates the thoroughness of the Ministry of Magic's operations and the constant effort required to uphold the International Statute of Secrecy. The Committee's work, as described by Arthur Weasley, adds depth to his character by showing the often-unglamorous but vital nature of his work within the Ministry, highlighting his dedication and the pressures he faces.
The Muggle-Worthy Excuse Committee is a detail found exclusively within the original novels. It is not mentioned or depicted in the film adaptations of the Harry Potter series.
