<s>[INST] The next text is a question of a member of the European parliament:"Since September2009, the Belgian National Service for Employees' Child Benefit (RKW) has been recovering payments of supplementary child benefit which — according to the Belgian authorities — have been wrongly paid in respect of children of parents living in the Netherlands, one of whom works as a frontier worker for an employer in Belgium and has social insurance cover there.  Under the Dutch Childcare Act, which entered into force on 1January2005, the Dutch tax authorities provide supplementary allowances such as supplementary child benefit, childcare allowance (KOT) and the ‘child-related budget’. Frontier workers too claim childcare allowance. At first the Social Insurance Bank took the view that these supplementary allowances could not be defined as ‘family benefits’ as referred to in Regulation (EC) No1408/71(1) (now Regulation (EC) No883/04(2)). However, the Commission took the view that childcare allowance was a family benefit and that no separate calculations were applicable for family benefits and child benefits.  Although it had originally been intended that the legislative amendment and the implementation of the coordination under the regulation should have retrospective force to 1January2005, the coordination provisions were not yet in force in 2005 and 2006. Only in the earlier part of 2007 did the Netherlands contact the Belgian National Service for Employees' Child Benefit about the matter, a fact which has not only resulted in delays in paying supplementary child benefit for the frontier workers concerned but also makes it extremely difficult to recover the wrongly paid amounts.  1.Is the Commission aware of this situation? If so, are further inquiries planned? If not, why not?  2.Will the Commission take steps to ensure that the transitional period entails less administrative obstacles? If so, what steps? If not, why not?    (1)OJ L 148, 5.6.1974, p. 35.  (2)OJ L 166, 30.4.2004, p. 1."
