German law is characterized by its structure, precision, and comprehensive nature, emphasizing the protection of both parties in commercial transactions. The German Civil Code codifies principles of fairness, transparency, and contractual integrity. The principle of good faith under Section 242 of the BGB requires that prices be fair and reasonable, reflecting actual value rather than speculative market conditions. Consumer protection laws further reinforce the notion that prices should be objectively justified, not arbitrarily set based on market demand or negotiation skills.
