the complainant inform the mission of any new developments, or especially to inform the mission if the case is satisfactorily resolved. 3) Next steps The following chapters of Part II are designed to assist field operations in following up properly on individual complaints on the basis of the information collected. Chapter 5 provides basic background on OSCE human rights commitments and other international human rights standards intended to help field operations make a sound preliminary assessment as to whether an individual complaint constitutes a human rights violation that could merit further action by the mission. In the event the mission decides to secure further information on a specific individual complaint, Chapter 6 provides guidance on conducting an interview, and Chapter 7 provides guidance on conducting an investigation. The mission may decide at any stage of this process that it has sufficient information to raise a case with government authorities or to take other forms of action. Part III of the handbook discusses various options for action available to OSCE missions. 4) Cases that are not taken up There may be a number of cases that the missions choose not to take up. The reason for such a decision may be that the case does not involve a human rights violation, that pursuing the complaint is beyond the mandate or resources of the mission, or that there are effective domestic remedies available that have not been pursued. A mission may also judge that a complaint is not sufficiently credible or substantiated, e.g., it is internally inconsistent in significant ways, it contradicts other facts known to the mission, or it appears to be politically motivated. In other instances, a different international organization may be better placed to deal with the complaint. For example, if the complaint concerns treatment of refugees, it is more appropriate to direct it to the local representative of the UN High Commissioner for Refugees, or, if it concerns treatment of a prisoner, the ICRC may better suited to follow up. 39 4
