The [[:CategoryKategori:LawHukum]] is a broad one that includes everything about law. Any article in any of its many sub-categories is implicitly included in this top category. Similarly, articles in lower level sub-categories are implicitly included in their parent categories, and do not need to be separately listed there. That said, no-one should ever be faulted for initially listing an article in a higher category than necessary; a person more familiar with the categories can always fix this later.
There are two major ways to divide the top category: geographically and by topic. The geographic division should take precedence when the work being categorized is all or disproportionately about that territory.
