Under these particular facts, a city may contract with an alderman’s employer where the alderman will have no personal involvement in performing the contract, will receive no personal benefit from the contract and where the contractor is a large, regional corporation which is one of two or fewer sources for necessary goods and services. The alderman will not have a prohibited interest in the contract between the city and the contractor, and no violation of Section 109, Miss. Const. of 1890, or Section 25-4-105(2), Miss. Code of 1972, will result. The exception codified in Section 25-4-105(4)(d) will prevent a violation of Section 25-4-105(3)(a), and the alderman’s recusal will avoid any violation of Section 25-4-105(1).
