The All Progressives Congress (APC) has released nine guidelines for the conduct of presidential, governorship and parliamentary aspirants ahead of primaries.
Aspirants are expected to sign undertakings to accept the outcomes of the shadow polls and support whoever emerges as a candidate for the general election.
The ruling party also directed them to take oaths not to engage in thuggery, anti-party activities, factionalisation or the creation of parallel congresses and party organs at any level.
The contenders have been barred from going to court without first exhausting avenues for redress and ventilation of grievances.
