7-8kgs are OK, but it does depend on drum size. If a 7kg washing machine's drum is smaller than a 5kg's drum, then that's silly. Of course some people are big families and do require large loads, hence there are needs for a larger washing machine.
Subject-matter jurisdiction. Subject-matter jurisdiction is the authority of a court to hear cases of a particular type or cases relating to a specific subject matter. For instance, bankruptcy court only has the authority to hear bankruptcy cases.
There are several forms of subject-matter jurisdiction, but the two most commonly appealed to are federal-question jurisdiction and diversity jurisdiction. Federal question jurisdiction is available when the plaintiff raises a claim that arises under the laws, treaties, or Constitution of the United States, as opposed to claims arising under state law.
