Facts:

The DOJ Panel found probable cause for the crime of rape with homicide against Hubert Webb. Webb claimed that the DOJ Panel gravely abused its discretion when the latter refused to call the NBI witnesses for clarificatory questions. Is Webb correct?

Held: 

A finding of probable cause needs only to rest on evidence showing that more likely than not a crime has been committed and was committed by the suspects. Probable cause need not be based on clear and convincing evidence of guilt, neither on evidence establishing guilt beyond reasonable doubt and definitely, not on evidence establishing absolute certainty of guilt. As well put in Brinegar v. United States, while probable cause demands more than "bare suspicion," it requires "less than evidence which would justify . . . conviction." A finding of probable cause merely binds over the suspect to stand trial. It is not a pronouncement of guilt.

Considering the low quantum and quality of evidence needed to support a finding of probable cause, we also hold that the DOJ Panel did not, gravely abuse its discretion in refusing to call the NBI witnesses for clarificatory questions. The decision to call witnesses for clarificatory questions is addressed to the sound discretion of the investigator and the investigator alone. If the evidence on hand already yields a probable cause, the investigator need not hold a clarificatory hearing. To repeat, probable cause merely implies probability of guilt and should be determined in a summary manner. Preliminary investigation is not a part of trial and it is only in a trial where an accused can demand the full exercise of his rights, such as the right to confront and cross-examine his accusers to establish his innocence. In the case at bar, the DOJ Panel correctly adjudged that enough evidence had been adduced to establish probable cause and clarificatory hearing was unnecessary. (Webb vs. De Leon, G.R. No. 121234 August 23, 1995)
