Based on constitutionality the multiplicity of interests and multiplicity of sects provides in part the solution to faction.
This is based on the idea that when there are multiple interests, and multiple sects, it would be difficult for a majority to occur which will then dominate the minority.
Also, multiple interests and multiple sects are characteristics of a large Republic that will prevent the rise of tyranny from the majority group which will then oppress the minority group.
This is because the multiple sects and multiple interests would need to constantly come together and embrace compromise and alliance.
Therefore, it would be difficult to have long-term factions as there would be competing interests.
Hence, in this case, it is concluded that the multiplicity of interests and multiplicity of sects provides in part the solution to the issue of "dominance of majority group and oppression of minority group."
