Yes, but they must not be granted that. What you said is correct, but people might interpret it as an absolute right to be released at some point.
The court mostly ruled that we must not have a situation like in America where elected politicians who are driven by populism decide on it. It must be legal proceedings in a regular court.
BTW, there is an interesting decision by our Constitution Court that touches on this and shows (IMO) an eminently sensible way and a willingness to cooperate with other legal systems. Anyone interested in a story? :-)
