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 is the aligning of vibrations in a transverse wave, usually by filtering out waves of other directions. Polarized light waves only travel vertically or horizontally -- when combined at right angles they block each other out and no net light can be detected.olarization is possible only when the direction of vibration is perpendicular to the direction of the wave travel, such is in light. In sound waves, the dire â¦ ction of vibration (compression) is the same direction as the direction of the travel of the sound wave, and therefore polarization is not possible.
