Do you agree that, if she said she was raped and she was telling the truth then rape occurred?
There are various elements of the crime of rape in English law. I do not know the details of how rape is prosecuted or defended in Cyprus - but it appears lack of consent is one element, same as in English law.
In English law - the mens rea element required for rape means she could be telling the truth that she did not consent but the prosecution would still need to show that the boys who had sex with her did not reasonably believe that she consented to the sex in order for them to have committed the crime of rape.
The 'reasonable belief' element means that it is not what the boys actually believed at the time that is important but whether a reasonable person in the same circumstances would believe that she was not consenting to sex when he was having sex with her. I think I am fairly safe in assuming that a reasonable person would not believe they had her consent if they had to hold the girl down in order to have sex with her.
However, in English law if the boys have evidence to show
it was reasonable for them to believe that she consented to the sex, then they do
not have the mens rea for rape.
Even if she froze, or was not forceful in fighting back, in English law the boys would still need to show they took steps to establish her consent to sex. In English law the burden is on the boys to show their belief in her consent is reasonable and it is up to the jury to decide based on the evidence, if the belief was indeed reasonable. I do not know where the burden of proof is in Cyprus law in relation to consent and what the boys believed at the time they had sex with her, and whether there is an objective element that their belief in her consent was reasonable.
