The testimony in a criminal case can be divided into two types:
1 – The direct testimony: It is the testimony that results from the direct contact of the witness’s senses, as if he witnessed a specific crime occurring.
2. The indirect testimony: It is the testimony in which the witness relates what was heard from others, and this testimony alone does not serve as proof in the evidence.
Persons prevented from testifying in criminal cases are:
1. The ascendants of the defendant (father, grandfather …. etc.)
2. The defendant’s descendants (son, grandson, etc.)
3. The defendant’s brothers and sisters.
4. Close relationship with those who are in the degree of brotherhood and sisters (the second degree in the relationship).
Husband and wife, even after divorce.
