In Germany, faulty assembly instructions make the product itself defective. The rule has applied since the reform of the law of obligations on 1 January 2002. Lawyers and consumer guides call it the Ikea-Klausel, the IKEA clause. Under Section 434 of the Civil Code, goods are free of defects only if they come with the assembly or installation instructions a buyer can expect. A wardrobe assembled wrongly because of a mistake in the seller’s instructions counts as defective goods. Where rules must be followed in use, the Product Safety Act also requires instructions in deutscher Sprache, in German.
