More than 550 hajj pilgrims die in Mecca as temperatures exceed 50C | At least 320 of the dead are from Egypt and Saudi officials report treating more than 2,000 people for heat stress
That their royalty are cowards doesn't stop them from being a sovereign country. Just what, exactly, do you think a lawyer can accomplish? The UN doesn't announce a global embargo on the lifeblood of modern nations because someone points out they violated a substatute.
For example, Oil and Gas Company Weatherford operates in 75 countries. Al Mansoori also has a wider base of operations. Also, again, if lawyers and journalists are so harmless to the GREAT AND POWERFUL ROYAL OVERLORDS™ then nobody would ever need to be butchered. If a large number of people, say hundreds of affected families, in a class action lawsuit all get butchered at once then even Royalty is going to have a very hard time both domestic and abroad.
