The ability to delegate some of ones activities to other organizations is something that has been used for many years by different types of organizations in different areas. This type of delegation to make use of external knowledge has been found to have many benefits such as improved quality of decision making,shorter decision paths and redistribution of resources to improve processes. Unfortunately, it has also been found that in some activities, delegation can lead to problems with, for example, information access. The purpose of this paper was therefore to investigate whether one authority's delegation of activities to another organization affects access to information based on the concept of public documents. The research questions that formed the basis of the investigation were 1) Are there information losses, based on the concept of public documents, that can arise in connection with the delegated activity, and which are they? and 2) What consequences can information loss have when looking at the principle of public access to official records? This paper has had a qualitative approach where interviews and document studies have been used as methods for gathering information regarding the two research questions. The main conclusion drawn from this thesis is that if the Swedish Transport Agency uses certain types of organizations for delegation of activities, extensive information loss can be incurred regarding information linked to certain parts of its activities and as an authority run the risk of being in conflict with the principle of public access to official records.
