Thorne v Motor Trade Association [1937]

In Thorne v Motor Trade Association [1937] AC 797, heard in the House of Lords, the central issue involved a motor trader who was found to be involved in price-fixing, contravening the regulations of the Trade Association to which he belonged. In response to this violation, the Trade Association provided the trader with an option: either pay a fine or face placement on a stop list, which would effectively hinder his business activities.

The Trade Association was deemed to have the right to place the motor trader on the stop list as a disciplinary measure for the breach of price-fixing rules. Additionally, the Association was held to have the right to demand a monetary payment as an alternative to being included on the stop list. Importantly, the court noted that had the fine been set at an exorbitant or extortionate rate, the legal position might have been different.

Lord Wright, in his reasoning, emphasised the broad interpretation of the term "menace". He opined that 'menace' should not be narrowly construed and limited to threats of physical violence. Instead, it should be understood as encompassing threats of any action that is detrimental or unpleasant to the person addressed. Lord Wright further noted that 'menace' might also include a warning that certain actions are intended in specific events.

In essence, Thorne v Motor Trade Association established that, within the context of a Trade Association, the imposition of a fine and the option of placement on a stop list were legitimate disciplinary measures for addressing breaches of association rules. The court's acknowledgment that an excessive fine might alter the legal analysis underscores the importance of reasonableness in the application of such disciplinary actions. Lord Wright's expansive interpretation of "menace" also broadens the scope of what actions may be considered coercive or threatening in legal terms.
