* Obesity not a specific disability in EU law
* But obesity can be a disability in some cases
* Case stemmed from dismissal of obese Danish child-minder (Adds detail, lawyer comments)

BRUSSELS, Dec 18 (Reuters) - Europe's top court ruled on Thursday that obese people can be considered as disabled, but stopped short of saying that obesity was a condition that needed specific protection under European anti-discrimination laws.
The landmark decision will be closely read by European employers and means that companies might have to provide greater support to obese staff.
The case was instigated by a Danish court, which wanted guidance over a complaint of unfair dismissal brought by a child-minder who was sacked by a local authority.
Karsten Kaltoft, who never weighed less than 160 kilograms (352 pounds) during his employment, argued that his obesity was one of the reasons he lost his job and that this amounted to unlawful discrimination -- an allegation the council denied.
The Court of Justice of the European Union (EJC) ruled that EU employment law did not specifically prohibit discrimination on the grounds of obesity, and said the law should not be extended to make it a protected category.
However, the Luxembourg-based court said that if an employee's obesity hindered "full and effective participation of that person in professional life on an equal basis with other workers" then it could be considered a disability. This, in turn, is covered by anti-discrimination legislation.
Classifying obesity as a protected characteristic -- such as sex, race or age -- would have required employers to take measures to ensure obese workers could perform their duties on an equal footing with others.
"It would have opened a can of worms," said Crowley Woodford, employment partner at law firm Ashurst.
However, Friday's nuanced ruling still leaves companies open to potential discrimination suits.
"If you consider the obese disabled, all of a sudden it triggers certain protections for employees," said Jacob Sand, a partner at Danish law firm Gorrissen Federspiel which represented Kaltoft.
Considering obesity a disability also reverses the burden of proof in workplace disputes over discrimination, Sand added, meaning it will be easier for employees to argue they had been discriminated against on the basis of their disability.
"That makes it a whole lot easier for employees in that it is easier to win the case," Sand said.
However it does not mean that employers cannot fire someone whose size means that they are unable to do their job, rather that they must consider whether any adjustments need to be made to help the employee perform their role first, said Stefan Martin, employment partner at law firm Mayer Brown.
According to statistics from the World Health Organization (WHO), based on 2008 estimates, roughly 23 percent of European women and 20 percent of European men were obese.
The issue of whether obesity is a disability has also been dealt with in U.S. courts, where almost one in three adults is obese, according to WHO data. Some states, such as Michigan, have enacted legislation that explicitly prohibits discrimination on the basis of a person's weight.
The Danish court must now decide whether Kaltoft's obesity represented a disability. It is expected to reach a decision before the end of next year. Kaltoft had asked for compensation equivalent to 15 months' salary for his dismissal, Sand said. (Reporting by Julia Fioretti; Editing by Philip Blenkinsop and Crispian Balmer)
