Whenever, in the judgment of the Board, the Common Elements require improvements, repairs or reconstruction costing in excess of Ten Thousand dollars ($10,000.00), adjusted by the percentage by which Common Expense Assessments have changed between 1985 and the year in which the Board wishes to make a special assessment, said improvements shall not be made unless they have been approved by two thirds (2/3) of the votes cast in person or by proxy at a meeting of the Unit Owners at which a quorum is present. Written notice of such meeting shall be sent to all Unit Owners at least thirty (30) days in advance and shall set forth the purpose of the meeting. The Board may incur expenses for improvements, repairs or reconstruction costing less than ten thousand dollars ($10,000.00), as adjusted herein, without the approval of the Unit Owners. Notwithstanding any of the foregoing, in the event of any emergency which could cause damage to the Building or any part (S) thereof, the Board may expend such sums as are necessary to protect the Building or part(s). The judgment of the Board in exercising its discretion hereunder shall be final.
