Is it a standard Wikipedia procedure to move pages from the Wikipedia namespace to meta? If so, who has decided this? And is it allowed for other languages to decide differently?
What kind of pages do you mean? Stuff generally gets transwikied to meta if it's not really about Wikipedia but more about the community. What do you mean by other languages deciding differently? To not transfer stuff to meta? I don't think it's a dictated policy by Jimbo so I reckon you can do what you like with it.
