The County Council functions in many roles. One role is as the legislative branch of government and when sitting as the legislative branch the Council members may discuss legislative issues with constituents. However, when the Council sits as the Zoning Board of Appeals, the Council members are functioning as a quasi-judicial board whose duty is to interpret the zoning law. In interpreting the zoning law, the Board may only consider the law and facts which are included in the record of the case. If a Council member has outside knowledge of a zoning case, the member may be obligated to refuse to participate in that zoning case. Also, the Harford County Charter, 706(b), prohibits an individual from influencing or attempting to influence, directly or indirectly, a member of the Board of Appeals in arriving at a decision in any pending zoning case.
