FOURTEENTH CONGRESS OF THE 
REPUBLIC OF THE PHILIPPINES 
First Regular Session 
INTRODUCED BY SEN. MANNY VILLAR 
EXPLANATORY NOTE 
Before a person is convicted and if he cannot afford bail or if his criminal 
case is one which is not bailable under the law, he undergoes preventive 
imprisonment. The present law provides that one must voluntarily agree in writing 
that he will abide by the same disciplinary rules imposed upon convicted 
prisoners and the same disciplinary rules imposed upon convicted prisoners and 
if no such written agreement is made, he will only be entitled to four-fifths of the 
period of detention. Review of many cases of prisoners show that this written 
agreement is often not completed for many reasons: (a) the apprehending 
officers do not know this provision of law or have no forms; (b) the prisoner 
himself is not aware of the requirement; or (c) neglect on the part of the prison 
officials such that the written agreement may be lost or misplaced. It has been 
the considered view of the Board of Pardons and Parole who review the cases of 
prisoners that the legal requirement should be reversed. The prisoner should be 
entitled in full for preventive imprisonment, except in cases specifically provided 
by law, without any written agreement. Only if he does not agree to abide with 
such rules, should be required to do so in writing and then he shall be entitled to 
only four-fifths of the period of detention. 
Thus measure seeks to correct this wrong procedure and thus gives the 
offender full credit for his preventive imprisonment as the general rule without 
any written agreement. 
Another case of injustice is when a prisoner has undergone preventive 
imprisonment for the possible maximum imprisonment of the offenses charged 
and he is not released. A paragraph under Article 29 by virtue of Batas 
Pambansa Blg. 85 corrects this injustice. However, the amendment needs further 
refinement. The offender under detention should not undergo detention more 
than such maximum, it should be equal to the possible maximum imprisonment. 
Moreover, since if the prisoner were to be convicted, he would enjoy good 
conduct time allowance for actual period of detention, then the computation for 
purposes of immediate release should be the actual period of detention .plus 
good conduct time allowance = maximum possible imprisonment. It is unjust to 
unduly delay the proceedings of a person already under detention. He should be 
given every possible opportunity to enjoy the benefit of law. If good conduct time 


allowance is granted to convicted prisoners, this benefit should also be extended 
to the detention prisoner under Article 29 as amended by Eatas Pambansa Blg. 
85. 
Every day that a prisoner stays in prison when he should have been 
released is justice delayed and denied. Approval of this measure is urgently 
requested.
