In the Federal Republic of Germany, the Ladenschlussgesetz or "Shop Closing Law" (abbreviated: LadSchlG) is the federal "blue law" compelling retail stores to close to the public on Sundays and Christian holidays. The Ladenschlussgesetz in its current form was first enacted on 28 November 1956 following pressure from Germany's trade unions; in its last revision (of 2 June 2003), points of sale (Verkaufsstellen) must be closed at any of the following times:
On working days (Monday through Saturday) before 06:00 and after 20:00;
On 24 December before 06:00 and after 14:00 if that date falls on a working day
The law provides differing regulations for pharmacies, petrol stations, shops at train stations and airports, etc.
On 30 June 2006, as part of the Föderalismusreform ("Federalism Reform"), the regulatory responsibility for this area was devolved to the German states. The net effect, although the Federal law technically remains in force, the states are free to determine the opening hours of retail stores in their areas. All states – with the exception of the more conservative Bavaria – have made use of that option.
The states have each adopted individual regulations concerning opening hours on Sundays and public holidays. Some continue to observe the existing Federal rules, while others have liberalized them somewhat, although the general Federal ban concerning opening on Sundays and holidays remains in effect, owing to a provision in the German constitution recognizing Sunday as a day of rest and a corresponding decision of the Federal Constitutional Court (Bundesverfassungsgericht) on 9 June 2004.
