Have you received a warning letter?
A cease-and-desist letter is often a burden for companies and requires swift action.

If a cease-and-desist declaration is demanded, we ensure that your company is not unduly burdened.
Temporary Restraining Order and Lawsuit
A preliminary injunction following a cease-and-desist letter requires swift action, as it can trigger drastic measures such as sales bans. Our law firm helps you defend against such injunctions or challenge them in court. We provide comprehensive representation throughout the proceedings, advise you on filing objections and challenges, and stand by your side during the main proceedings to protect your interests.

Frequently Asked Questions About Cease-and-Desist Letters and Preliminary Injunctions
1. What is a warning letter, and what does it mean for my company?
A cease-and-desist letter is an out-of-court request to refrain from a specific course of conduct, such as misleading advertising. Its purpose is to avoid disputes without immediately initiating legal proceedings.
2. How should I respond to a cease-and-desist letter?
Review the warning letter immediately and make a note of the deadline for responding. Contact a lawyer who specializes in this area before signing a cease-and-desist letter, as this can have far-reaching consequences.
3. What is a preliminary injunction under competition law?
A preliminary injunction is a court order issued quickly to halt a violation of competition law on short notice. It may include sales bans, advertising restrictions, or product recalls.
4. What happens if I ignore a temporary restraining order?
Failing to comply with a preliminary injunction can have serious consequences, such as hefty fines or even imprisonment for company executives. It is therefore essential to take action promptly.
5. Do I always have to respond to a warning letter?
Yes, it is advisable to respond. If you ignore a cease-and-desist letter, the sender can apply for a preliminary injunction. In some cases, however, it is possible to contest the cease-and-desist letter.
6. What are the time limits for a cease-and-desist letter and a preliminary injunction?
The deadlines for cease-and-desist letters are often very short, typically just a few days. For preliminary injunctions, there are also tight deadlines for filing objections and appeals, which are usually specified in the injunction itself.
7. How much does a cease-and-desist letter or preliminary injunction cost?
The costs depend on the amount in dispute, which is specified in the cease-and-desist letter or order. Recipients of cease-and-desist letters are often required to pay the opposing party’s attorney’s fees if the cease-and-desist letter is justified.
8. What does it mean to sign a cease-and-desist letter?
By signing the cease-and-desist letter, you agree to refrain from the disputed conduct in the future. However, it may result in contractual penalties in the event of violations, which is why it must be worded carefully.
9. What are market conduct rules?
Market conduct rules are legal regulations that ensure fair competition, such as the Price Indication Regulation, the Packaging Act, or the Law on the Advertising of Medicines. Violations can result in warning letters.
10. What typical violations of market conduct rules result in warning letters?
Common cease-and-desist letters concern misleading advertising, incorrect price listings, incorrect product labeling, and unauthorized health claims.
11. Can I contest a cease-and-desist letter or a preliminary injunction?
Yes, in many cases there are defense strategies. A specialized attorney will assess whether the cease-and-desist letter is justified and whether it makes sense to mount a defense.
12. How does a proceeding for a temporary restraining order work?
The procedure is generally expedited. The petitioner files the petition with the court, and the court usually renders a decision without hearing the respondent. However, it is possible to appeal the decision.
13. Can I be sued for damages after receiving a warning letter?
Yes, in cases of antitrust violations, competitors may, under certain circumstances, assert claims for damages, particularly if they have suffered financial losses as a result of the conduct in question.
14. How can I protect my business from future cease-and-desist letters?
By conducting regular legal reviews of your marketing activities, product labeling, and terms and conditions, you can avoid potential violations.
15. Why are warning letters frequently issued in online retail?
Online retailers must comply with numerous rules governing market conduct, such as transparent pricing and complete product labeling. Violations are often quickly detected and result in warnings.
