A long line of Supreme Court precedent adheres to that fundamental principle in unequivocal language. That's an unequivocal, categorical, and blanket protection against discrimination. The decision to do so should be "unequivocal and unconditional" and "follow a democratic process". Early cases indicated that there had to be a clear and unequivocal undertaking. A waiver must also be clear and unequivocal. The state of irreversible brain damage has to be unequivocal. Officers knew the dangers of this restraint but chose to go against clear, unequivocal training. The introduction of agriculture has not necessarily led to unequivocal progress. Witnesses report an expression of "unequivocal indignation" on her face when her cheek was slapped. The oldest unequivocal evidence of betel chewing is from the Philippines. The only unequivocal method of resolving phase ambiguity is by sequencing. Since there is no unequivocal definition of life, most current definitions in biology are descriptive. It does not appear that either side is making unequivocal progress. There is no unequivocal European record from the Neogene. The answer, for me, is an unequivocal "no".
