What is a Search Order (Anton Piller Order)?
A Search Order, historically termed an Anton Piller Order, is a powerful legal tool within the English and Welsh legal systems. It allows for the preservation of evidence that might be vital in legal proceedings, particularly in cases concerning the infringement of intellectual property rights or the misappropriation of confidential information. Essentially, it permits the applicant, typically a business, to enter the premises of the alleged infringer to search for, copy, and remove documents or materials relevant to the case.
This type of order is granted without prior notice to the respondent (the party against whom the order is issued), making it a drastic but sometimes necessary action to prevent the potential destruction or concealment of evidence. Given its intrusive nature, a Search Order is only issued under stringent conditions and when there is clear evidence of a serious infringement.
Understanding the Legal Basis of Anton Piller Orders
The legal foundation of Anton Piller Orders lies within the Civil Procedure Rules (CPR) and the inherent jurisdiction of the High Court. The landmark case of Anton Piller KG v Manufacturing Processes Ltd (1976) established the precedent for these orders, hence the nomenclature. The principle behind issuing such an order is the preservation of evidence that is in danger of being destroyed, altered, or hidden by the respondent.
To obtain an Anton Piller Order, the applicant must convincingly demonstrate to the court that:
- There is an extremely strong prima facie case.
- The damage, potential or actual, must be very serious for the applicant.
- There is clear evidence that the respondents possess incriminating documents or items, and there is a real possibility that they may destroy such material before any application inter partes can be made.
The court exercises its discretion with extreme caution, balancing the need to preserve evidence with the potential for injustice or undue harm to the respondent.

The Process of Obtaining a Search Order in Court
Obtaining a Search Order is a complex and urgent legal procedure that requires meticulous preparation and a compelling presentation of evidence. The process typically involves the following steps:
- Preparation of Evidence: The applicant must compile a comprehensive affidavit detailing the facts of the case, the necessity for the Search Order, and evidence supporting the claims of potential harm or destruction of evidence.
- Ex Parte Application: The initial application for a Search Order is made ex parte, meaning without the presence or knowledge of the respondent. This is to prevent the destruction of evidence once the respondent becomes aware of the proceedings.
- Court Hearing: The applicant’s legal team must present the case to a judge, arguing why a Search Order is necessary and justifiable. This includes demonstrating the urgent need for the order, the likelihood of success on the merits of the case, and the proportionality of the order in the circumstances.
- Issuance of the Order: If the judge is convinced, the order will be issued. It will detail the scope of the search, the manner in which it must be conducted, and any limitations or protections for the respondent.
Given the expedited and sensitive nature of this process, businesses typically require the assistance of experienced legal counsel to navigate the complexities involved.
Your Rights and Obligations Under a Search Order
Once a Search Order has been issued, it is crucial for both the applicant and the respondent to understand their rights and obligations. For the applicant, there is a duty to conduct the search fairly and responsibly, adhering strictly to the terms set out in the order. This includes conducting the search at reasonable hours, making a detailed inventory of the items taken, and respecting the confidentiality of the information discovered.
The respondent, on the other hand, is obligated to comply with the order but also retains certain rights. These include the right to have a legal representative present during the search and the right to claim privilege over certain documents. It is also within the respondent’s rights to apply to the court to vary or discharge the order if they believe it to be unjust or improperly granted.
Executing a Search Order: Steps for Businesses
The execution of a Search Order is a critical moment that requires careful planning and sensitivity. For businesses tasked with executing an order, the following steps are recommended:
- Assemble a Search Team: This should include legal counsel, an independent supervising solicitor appointed by the court to ensure fairness, and any necessary technical experts.
- Initial Meeting: Before executing the order, hold a briefing to review the order’s scope, the rights and obligations of all parties, and the logistics of the search.
- Notification and Entry: The supervising solicitor first notifies the respondent of the order and requests entry. If entry is refused, the order allows for forced entry, but this should be a last resort.
- Conducting the Search: The search must be conducted efficiently, respectfully, and within the scope of the order. Documents and materials identified as relevant should be copied or seized, with a detailed inventory kept.
- Post-Search Procedures: After the search, provide the respondent with a copy of the inventory and ensure that any seized items are stored securely.
Given the potential for conflict and the need for meticulous adherence to legal procedures, the role of experienced legal counsel cannot be overstated.
How a Lawyer Can Help with Search Orders
The complexity and high stakes involved in obtaining and executing a Search Order necessitate professional legal assistance. A lawyer specializing in intellectual property or commercial litigation can provide invaluable support in several ways:
- Advice and Assessment: They can assess the merits of your case and advise whether a Search Order is an appropriate and viable option.
- Preparation of Application: Lawyers can help in drafting the detailed affidavit required, ensuring that it meets the stringent criteria set by the courts.
- Representation in Court: Expert legal representation is critical during the ex parte hearing to persuasively argue the need for the order.
- Guidance on Execution: Lawyers can guide the search team on the proper execution of the order, ensuring compliance with legal requirements and minimizing potential liabilities.
- Post-Search Handling: Post-execution, lawyers can assist in analyzing the seized evidence, preparing for further legal actions, and dealing with any challenges to the order.
In summary, while a Search Order is a potent tool for protecting a business’s interests, it comes with significant responsibilities and legal complexities. Professional legal guidance is essential at every step to ensure that the process is handled correctly, fairly, and effectively.
