1. Introduction Max Weber (1968) was first to introduce issue of division of work and link it to related issue of power. Organisational divisions may have different tasks, but they are usually interdependent. Staff from various departments participate in a decision-making process. Each sub-group has its own goals and personal needs of its members, as well as objectives set by formal structure. The existence of varying sub-goals, and absence of clear and agreed aspirations about future due to uncertainty in making decisions, are major causes of conflict during decision process (Allison 1969; Ntanos 2009). During process, sub-groups express their interests by making demands on organisational scarce resources, and advancing these demands in bargaining arena. A demand is feasible only when sufficient power is mobilised in support of that demand. By holding resources, individual causes a dependency situation that secures his/her position and increases his/her power basis, especially in conditions of organisational change. Pettigrew (1973) argues that control of organisational resources increases holders' power base and ability to influence decisions and allows partial goals to be served. Within an organisation individual is not only governed by organisational structure, but also attempts to shape structure over time to suit his/her own interests and needs. The ability to influence organisational structure is a function of power generated by individual in order to impose on others his/her will. Power is not a matter of authority or status, but rather has to do with control of resources and information, and skilful use of them. Therefore, Power is not only seen as operating vertically in hierarchy, but power relations also may exist among 'equal' standing individuals or sub-units (Pfeffer 1981). Power, though affecting broad areas of organisational domain, was neglected as a subject of study for a long period of time for various reasons (Pfeffer 1981). First, it is a concept that has attracted various interpretations in social science literature, and so could be characterised as problematic. As a way of understanding organisational decision-making, it is not unique. Other perspectives exist that attract researchers because they do not confront notion of rationality and existence of commonly accepted organisational goals seeking efficiency. Finally, admitting existence of power relations and of sectional interests, may undermine notion of cohesion in an organisation. This paper aims to raise neglected role of power politics in organisational decision-making. Apart from purely rational perspective and bounded-rational perspective, there is a notion of rationality in political perspective of decision-making (Jones 1992). Rationality here refers to way in which each interest group conceives their surrounding context, faces uncertainty and responds to a perceived problem (Dermer & Lucas 1986). Within political perspective, rationality has not a neutral but an ideological intense meaning, since there are many views of what rational behaviour is, based on various interpretations of reality. We aim to depict that accounting information is used politically in order to forward a certain interpretation of reality as truth, usually most powerful interpretation. The role of accounting may therefore lie not on making rational decisions, but in helping politically made choices to be accepted. This does not imply that these decisions are irrational; on contrary, behind politically made decisions lies rational action from an interest group that is purposefully pursuing solution best suited to its own aims. 2. The Definition of Power Pfeffer referred to power as the capability of one social actor to overcome resistance in achieving a desired objective or result (1981, p. …
