"It is no different with the judge that is going to make a decision on edig. Its all based on opinion, Not law."
Judges use previous cases, legislated law, and the evidence that supports both side's contentions that is allowed for direction. Each side create briefs that cite the cases that support their side. Judges do not rely on their opinions--only to the extent they interpret the documents and citations. This is what having independant judges is all about. ORY
