::The problem with the article is that it's trying to cover the concept of appeal in the entire English-speaking world, while a lot of the things it says are limited in geographic scope but the article does not point that out. Therefore the article is likely to be confusing to a layperson. For example  the term "appellee" is a purely American term but the article implies that it is used everywhere. The business about filing a notice of appeal with the court from which you are appealing is not universal either. Sentences like "And due to the double jeopardy principle, the state or prosecution may never appeal a jury or bench verdict" are not true for all countries.
