Key legal question
Whether a valid removal order existed to support deportation detention after the appellant's departure from Switzerland.
Extracted holding
No. The earlier removal order had lapsed upon the appellant's departure, so it could no longer support deportation detention.
Extracted reasoning
Self-initiated departure executes the removal order; after re-entry, a new removal decision is required. The appellant made credible his departure abroad, so the 2001 removal decision no longer existed as a basis for detention.
