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.
In classical electromagnetism, polarization density is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the dielectric is said to be polarized. The electric dipole moment induced per unit volume of the dielectric material is called the electric polarization of the dielectric. Polarization density also describes how a materia
