OUSU Council provides Policy Guidelines for how the Student Union is run.

Policy Guidelines can range from whether OUSU should support a national demonstration against a government policy to whether it should refrain from advertising or purchasing certain products because of the working conditions of the labourers who produce them.
OUSU's current Policy Guidelines Book can be read here.

If you're interested in proposing a motion to OUSU Council, whether to establish Policy Guidelines or on a more specific, self-contained issue, click here. Further details of the effect and function of Policy Guidelines can be found in Bye-Law 11 of the OUSU Bye-Laws.
