SACCORD Executive Director Boniface Cheembe has questioned which part of the constitution would allow such an arrangement.
Mr Cheembe has told Qfm News that NAREP should clarify which part of the republican constitution provides for an interim President who should be in office for only 9 months with a specific duty of ensuring the enactment of a constitution.
Mr. Cheembe also wonders whether there will be willingness from all political stakeholders in the country if ever such a process is pushed through.
And the Young African Leaders Initiative (YALI) says the NAREP proposal does not legally and constitutionally hold any water.
YALI Governance Advisor Isaac Mwanza has told Qfm News in a separate interview that this is because the country already has a functional government and there is no way an interim government can be ushered in to serve a different purpose.
Mr. Mwanza has suggested that the only way forward with regards the enactment of a new constitution is continued dialogue among all stakeholders.
