In exceptional cases, other costs actually incurred by using such offerings can now, since August 2013, also be covered […]. […] 10 4. In the challenged provisions, the legislature has redrawn the assessment of standard needs following the decision of the Federal Constitutional Court of 9 February 2010 (Decisions of the Federal Constitutional Court, Entscheidungen des Bundesverfassungsgerichts – BVerfGE 125, 175). Standard needs are no longer set by means of regulation, or in an ordinance […], but […] set by a law passed by Parliament.

Nor are households removed of persons who have formerly received unemployment support or unemployment benefit or households that are in need of benefits to secure their subsistence but have not claimed such benefits (“hidden poverty”). 14 […] 15 b) Six levels of standard needs are determined on the basis of the consumer ex- 16 7/29
