In New Southern Railway Ltd v Quinn [2006] IRLR 606 EAT, the Employment Appeal Tribunal holds that an employer's duty to take steps to "avoid" risk to a pregnant woman means that the risk should be reduced to its lowest acceptable level - not that it must be removed completely.
In Hawley v Luminar Leisure and others [2006] EWCA Civ 18 CA, the Court of Appeal holds that responsibility for controlling a worker passed to his "temporary deemed employer", and it was unsuccessful in its attempt to persuade the court to make a finding of dual vicarious liability.
In Viasystems (Tyneside) Ltd v Thermal Transfer (Northern) Ltd and others, the Court of Appeal holds that more than one "employer" can be vicariously liable for the negligence of an employee, overturning a long-standing assumption that it is possible in law only for one employer to be so liable.
In Bunning v G T Bunning & Sons Ltd, the Court of Appeal holds that the tribunal was correct to find the employer in breach of its obligation to carry out a risk assessment for a pregnant worker under reg.16 of the Management of Health and Safety at Work Regulations 1999.
In Hartman v South Essex Mental Health and Community Care NHS Trust and other appeals, the Court of Appeal holds that, for a stress at work case to succeed, it must be shown that the injury was not too remote.
