Does the Federal Bureau of Prisons' commitment order violate an individual's constitutional right to personal liberty when imprisonment is based on offenses not formally charged or adjudicated?

QUESTION PRESENTED This Court has held that commitment for any purpose constitutes a significant deprivation of liberty that requires protection under the federal Constitution. Here, after Christian Womack was sentenced to natural-life imprisonment, on offenses that he was neither charged with by way of indictment, nor found guilty of, he was committed to the custody of the Federal Bureau of Prisons (FBOP) on those offenses. Does the FBOP's authority to restrain the body of Christian Womack under the District COurt's judgement of commitment order, thereby violate his right of personal liberty?
