Gamble v. Sears, 2007 MT 131, 337 Mont. 354, 160 P.2d 537 The Montana Supreme Court has held that substantial credible evidence is that which a reasonable mind could accept as adequate to support a conclusion. Indicating the high level of deference the court accords to the WCC’s factual findings, evidence will be considered substantial even if it is contradicted by other evidence, even if it is somewhat less than a preponderance, and even if it is inherently weak. However, it must be more than a mere “scintilla” and it must rise above the level of “trifling or frivolous.”
