The jurisdiction also demands sufficient evidences as far the defense lawyers are concerned. The work schedule of the defense lawyers is often bound with mere interrogation of the evidences placed by the prosecutor. But the major task of the defense lawyer is to frame certain evidences nullifying the effects of the evidences provided earlier.

The defense lawyers make use of the newer technologies such as the DNA test to some extent to establish certain relationship problems occur. If the nature of the case is such that the case demands the relationship between the accused and the evidence or witness, then DNA tests are carried out to mark the background of the evidence. Forensic departments also play a major role in the defense lawyers approach to the case.
