Please don't bend the facts for your own bias. The king doesn't appoint those judges, will just ratify and is pretty much symbolical. They do have political influence but is kept balance traditionally. Just because everyone has political inclinations you cannot blame it of being controled by the government.
8 of them are proposed by the legislative branch (parliament and senate), 2 by the executive, and 2 by the judicial.
Whether that makes the tribunal as a whole independent from the government or not is an opinion I leave to the reader.
