Scope and purpose
Statutory withholding under §241(b)(3) is distinct from asylum under INA §208 and from Convention Against Torture protection. Different burdens, bars and consequences apply; denying asylum does not by itself resolve every other protection claim.
Related rules and practical context
Zadvydas addresses a particular post-removal-order detention provision, not a universal release date. Nasrallah concerns judicial review of CAT orders. The governing detention authority and protection claim must be identified separately.
