cannot include anything irrelevant to the case, reference to compensation, letters of support from other people, or information on the development that will not help the arbiters in their purely analytical review. Participant writers have 24 hours to give their statements, their only means of providing supporting evidence to the arbiters, to the guild. Statements submitted late will be accepted as long as they come before a decision is made. The arbiters thus each receive the tentative writing credits, the writers' statements, a summary of the issues to be determined in the case, all the written material with a chronological record, a copy of the Screen/Television Credits Manual, and the request that their decision be communicated to the Screen/Television Credits Administrator first by telephone and then in writing. The writers' statements are kept private by the WGA. Additionally, the writers' identities are kept anonymous from the arbiters. In situations where there is doubt over the authenticity of the submitted written material, a hearing may be held before arbitration, where the writers each provide testimony and evidence as to the authorship, sequence, and legitimacy of the material. The Writers Guild may also request a descriptive script of a film called a "cutting continuity", or a television production called an "as broadcast" script, which the production must provide if available; particularly, a writer may ask that the Writers Guild request this if they believe the final script is not reflective of what was actually filmed. The arbiters may not come to unanimous agreement. When this happens, they teleconference with the advisor to, while remaining anonymous to each other, discuss the reasoning for their choices in an attempt to come to a decision. In the absence of a unanimous decision at this stage, a majority decision shall be accepted. The arbitration committee's decision, once written confirmation has been received by the Screen/Television Credits Administrator, is communicated to the interested parties. A participant writer may then request an appeal before an internal Policy Review Board of the Writers Guild, within 24 hours of the arbiters' decision being communicated to them. That board consists of three members of the Screen/Television Credits Committee, usually including either the Chair or Vice-Chair; none should have an interest in the decision. The Policy Review Board only serves to determine if there was any "serious deviation from the policy of the Guild or the procedure as set forth in [the
