1. See, e.g., 27 BVerfGE 1, 6(1969) (Microcensus): “It would be inconsistent with the principle of human dignity to require a person to record and register all aspects of his personality even though such an effort is carried out in the form of a statistical survey; [the state] may not treat a person as an object subject to an inventory of any kind.” The census questions in issue, which pertained to vacation habits, were held permissible.
2. See 24 BVerfGE 367, 400 (1968).
3. 6 BVerfGE 55, 70–84 (1957).
4. The civil and administrative courts, on the other hand, have developed an extensive jurisprudence for determining when regulation amounts to a taking; the problem has proved as refractory in Germany as it has in the United States. See Papier, Art. 14, in 2 Maunz/Dürig, Para. Nr. 291–450, arguing (Para. Nr. 449) for a test based upon the severity of the restriction (cf. Pennsylvania Coal Co. v. Mahon, 260 U.S. 393 (1922)); Leisner, in 6 Handbuch des Staatsrechts § 149, Para. Nr. 148–51, arguing that such a test should be complemented by special concern for those made to bear an undue share of the total burden (Sonderopfertheorie).
5. 45 BVerfGE at 245; see also id. at 228–29. As the quotation suggests, this decision was not based entirely on Article 1(1). See id. at 223, noting the obvious involvement of Article 2(2)'s right to personal liberty; id. at 239, concluding that the “interest in rehabilitation flows from Article 2(1) in tandem with Article 1.” In early days doubts had been expressed whether Article 1(1) was directly enforceable at all, partly because Article 1(3) made only the “following” basic rights binding on government organs as “directly enforceable law.” See, e.g., Dürig, Art. 1(1), in 1 Maunz/Dürig, Para. Nr. 4, 7 (adding, in Para. Nr. 13, 16, that it hardly mattered since the dignity principle had to be employed as a standard in interpreting other constitutional provisions as well as the ordinary law). For the contrary view, see Podlech, Art. 1(1), in 1 Luchterhand, Para. Nr. 61. To this date the Constitutional Court has never invalidated government action on the basis of Article 1(1) alone.
