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.
It is granted to a formally constituted legal body, such as a court, or to a political leader. It grants authority to deal with and make pronouncements on legal matters and, by implication, to administer justice. Jurisdiction has defined areas of responsibility, e.g. Michigan tax law. Areas of jurisdiction apply to local, state, and federal levels, e.g. the court has jurisdiction to apply federal law. Colloquially it is used to refer to the geographical area to which such authority applies, e.g. the court has jurisdiction over all of Colorado. The legal term refers only to the granted authority, not to a geographical area.
