Information provided to the Law Commission: We aim to be transparent in our decision- making, and to explain the basis on which we have reached conclusions. We may publish or disclose information you provide in response to Law Commission papers, including personal information. For example, we may publish an extract of your response in Law Commission publications, or publish the response itself. We may also share responses with Government. Additionally, we may be required to disclose the information, such as in accordance with the Freedom of Information Act 2000. We will process your personal data in accordance with the UK General Data Protection Regulation. Consultation responses are most effective where we are able to report which consultees responded to us, and what they said. You may want your response to be anonymous, for example because it contains sensitive information about you or your family, or because you are worried about other people knowing what you have said to us. If you ask us to treat your response anonymously, we may refer to what you say in your response, but will not reveal that the information came from you. Alternatively, if you consider that it is necessary for all or some of the information that you provide to be treated as confidential and so neither published nor disclosed, please contact us before sending it. Please limit the confidential material to the minimum, clearly identify it and explain why you want it to be confidential. We cannot guarantee that confidentiality can be maintained in all circumstances and an automatic disclaimer generated by your IT system will not be regarded as binding on the Law Commission. We list who responded to our consultations in our reports. If your response is anonymous we will not include your name in the list unless you have given us permission to do so. If you provide a confidential response your name will appear in that list. Further information about how we handle data is available at: https://www.lawcom.gov.uk/document/handling-data/.
