The arbitration board, acting through its chairperson, shall

call a hearing to be held within ten (10) days after the date of the

appointment of the chairperson and shall, acting through its

chairperson, give at least seven (7) days of notice in writing to

each of the other two arbitrators, the bargaining agent and the

corporate authorities of the time and place of such hearing. At

least seven (7) days before the date of the hearing the bargaining

agent and the corporate authorities shall submit to each other and

to the arbitration board members a written arbitration statement

listing all contract terms which the parties have resolved and all

contract issues which are unresolved. Each arbitration statement

shall also include a final offer on each unresolved issue. The

terms and offers contained in the arbitration statements shall be

known collectively as each parties’ last best offer. The hearing

shall be informal and the rules of evidence prevailing in judicial

proceedings shall not be binding. Any documentary evidence and

other data deemed relevant by the arbitrators may be received into

evidence. The arbitrators shall have the power to administer oaths

and to require by subpoena the attendance and testimony of

witnesses, the production of books, records, and other evidence

relative or pertinent to the issues presented to them for

determination. A hearing shall be concluded within twenty (20) days

from the time of commencement. Within seven (7) days after the

conclusion of the hearing, a majority of the arbitration board

members shall select one of the two last best offers as the contract

of the parties. The criteria to be used by the board in determining

which offer to select shall be limited to those in Section 6 of this

act. The arbitration board may not modify, add to or delete from

the last best offer of either party. Written notice of the

selection decision shall be mailed or delivered to the employer and

the union.
