"A person, who is thus interrogated, will be obligated to answer correctly all the questions that will be presented to him at the time of the interrogation by the same police officer, or by another authorized officer as aforesaid, except for questions whose answers would be sufficient to put him in danger of criminal guilt."
This right, not to answer questions during interrogation, is qualified in section 28(a) of the Criminal Procedure Law (Enforcement Powers – Arrests), 5756-1996, hereinafter: the Arrests Law) that there is a duty to inform a suspect of his right to remain silent and that if he chooses to respond, everything he says will be used against him (interrogation under warning).
"The officer in charge of the arrest of a person shall not decide on the continuation of his detention or his release on bail, and shall not determine the type, amount and conditions of the bail, without first giving that person an opportunity to make his statement, after being warned that he is not obliged to say anything that may incriminate him, that anything he says may serve as evidence against him, and that his refusal to answer questions may strengthen the evidence against him."
In other words, silence is permissible, but it may serve as evidentiary support against the interrogee.
In addition, Section 47 of the Evidence Ordinance [New Version], 5731-1971 (hereinafter: the Evidence Ordinance), entitled "Incriminating Evidence", applies to the proceedings in court and provides as follows:
")a) A person is not obligated to give evidence if it involves an admission of the fact that it is one of the foundations of an offense of which he is accused or may be accused of.
(b) If a person requests to refrain from providing evidence because it is likely to incriminate him as stated in subsection (a) and the court rejects the request and the evidence is provided, the evidence will not be presented against that person in the trial in which he is accused of the offense of which the fact revealed by the evidence is one of the foundations, unless he has consented to it.
