A party that the court feels is hostile against the party they are supposed to testify for. They can be cross examined if they are called. They can be impeached by their own credibility.
Polarize is to force a something or someone to go in only one direction, or to cause people to divide into two very distinct groups. 1  When a special microscope forces the transverse waves created by a light to be focused only in one direction, this is an example of when it polarizes. When a political leader pits one group of people in society against another using inflammatory speech, this is an example of when he polarizes the groups.
Polarization (also polarisation) is a property of some types of waves. Some waves have motion in another direction as well as the direction of the wave.In water, for instance, the wave will move across the water, but something on the surface of the water will move up and down.f both the electric field and magnetic field are perpendicular to the direction of the wave, the wave is called TEM (transverse electromagnetic). Linear, circular, and elliptical polarizations are specific cases of TEM polarization.
