Public bodies report that they cannot always share the data they need to share and, as a result, miss out on opportunities to provide better services to citizens. At the same time, the protection of privacy is fundamental to any data sharing regime. The law surrounding data sharing is complex. Powers to share data are scattered across a very large number of statutes and may be set out expressly or implied. In addition, there are common law powers. In this scoping project the Law Commission considered the following questions: are there hurdles to effective data sharing between public bodies (including private bodies engaged in public service delivery)?; Are those hurdles inappropriate?; How far do problems in data sharing stem from the law?; How far do problems in data sharing stem from other causes, such as a lack of training or guidance, organisational incentives and disincentives?; Would law reform solve or mitigate the problems? The Commission recommends that a full law reform project should be carried out in order to create a principled and clear legal structure for data sharing, which will meet the needs of society. The scope of the review should extend beyond data sharing between public bodies to the disclosure of information between public bodies and other organisations carrying out public functions.
