As long as there is a separate investigation to prove beyond a reasonable doubt that she was lying. Because a failed conviction is not proof or evidence that the accuser is lying. But such a law has to be approached really carefully, because any legislation that might disincentivize actual victims from speaking up should never even be entertained. The victim thinking that they were raped but the court finding she or he wasn't does not mean the victim lied. The wrong person being tried but the victim genuinely though that it was the perpetrator, also not a lie. Tldr: unfounded or no crime =/= malicious lie.
