Miss. Code Ann. § 19-13-55

No payment shall be made hereunder except by a four-fifths recorded vote of all the members of the board of supervisors. Where the property injured or destroyed is properly assessable, no evidence of the actual value of the property injured or destroyed shall be received or considered, but the assessed value thereof as shown by the assessment rolls of the county shall be the only evidence of value, and the damages allowed shall be fixed in proportion. Where the property injured or destroyed is not properly assessable and was not assessed, then the board of supervisors shall receive evidence of the actual value of the same, and shall allow damages in proportion. Sections 19-13-51 through 19-13-55 shall not be construed as creating any enforceable liability against any county.
