Overview of the Mersey Docks and Harbour Board Ltd v Coggins and Griffith case

In Mersey Docks and Harbour Board Ltd v Coggins and Griffith (Liverpool) Ltd [1946] 2 All ER 345 HL, the House of Lords held that where a crane was hired with a driver and that driver was negligent, the driver’s employer would be vicariously liable.
