False Rape Accusation: Criminal Defense

The false rape accusation is one of the most complex phenomena of contemporary criminal law. The accused simultaneously faces a serious criminal process —with penalties reaching 15 years of prison if penetration and aggravating factors of Art. 180 CP concur— and an immediate social stigmatization that operates as anticipated conviction before any judicial resolution. The presumption of innocence of Art. 24.2 of the Spanish Constitution is an inderogable constitutional rule, but its practical effectiveness requires active, not merely reactive, technical defense. Consolidated Supreme Court case-law establishes that the victim's statement, when the sole incriminating evidence, must meet three cumulative requirements: absence of subjective unreliability (absence of spurious motives such as custody, revenge, social pressure), objective plausibility (corroboration through peripheral elements) and persistence in incrimination (internal coherence without essential contradictions).

The typologies of false accusation identified by forensic psychological doctrine are recurrent. Accusations instrumentalized in family proceedings are the most frequent: conflictive separations, custody disputes, family-home attribution, where the accusation operates as a negotiating weapon to obtain advantages in civil proceedings. Accusations from post-encounter regret reclassify an initially consensual sexual act after intervention of external factors (steady partner, family pressure, social shame, unwanted pregnancy). Accusations from personal revenge arise after romantic breakups, job terminations, neighborhood or academic conflicts. Accusations from psychiatric disorders of the accuser, especially borderline personality disorders or psychoses, can distort reality perception. Accusations from economic blackmail seek civil compensation under pressure of criminal penalty.

The applicable criminal framework to the falsely accused is severe. The basic sexual assault (Art. 178 CP) carries 1 to 4 years' prison; with penetration (Art. 179 CP), 4 to 12 years; with aggravating factors of Art. 180 CP (special vulnerability, joint action, use of weapons), up to 15 years. The accessory consequences are devastating: mandatory registration in the Central Sex Offenders Registry (RD 1110/2015) for 20-30 years, disqualification for professions with minors, prohibition of approach to the accuser, 5 to 10 years' supervised release, asset garnishment for civil liability. The counter-action after acquittal is channeled through Art. 456 CP on false accusation or report, which punishes with 6 months to 2 years of prison or 12 to 24 months' fine whoever, with knowledge of falsehood or reckless disregard for truth, imputes to another person acts constituting criminal infraction. It is a complementary but complex route: it requires proving the subjective falsehood of the accuser, not the mere acquittal of the accused due to evidential insufficiency.

Specialized technical defense is built on four axes. First, the psychological credibility expert evidence: application of CBCA (Criteria-Based Content Analysis) and SVA (Statement Validity Analysis) protocols by qualified forensic psychologists analyzing internal consistency of testimony, presence of sensory details, reality versus invention criteria, and possible spurious motives. Second, the exhaustive digital forensic extraction: WhatsApp, Instagram DMs, Telegram, email, GPS geolocation from Google Timeline, photos with EXIF metadata, card records (taxis, hotels, restaurants); a cordial or affectionate message after the encounter can destroy the assault narrative. Third, the chronological factual reconstruction: urban and private video surveillance cameras, direct and indirect witnesses, verification of coincidence between the accuser's version and objective data. Fourth, the procedural and constitutional challenge: exercise of the right not to testify (Art. 24 of the Spanish Constitution), control of precautionary measures to avoid pretrial detention, presentation of exculpatory evidence in investigation phase, rigorous articulation of the defense brief.

In current forensic practice, alleged sexual assault proceedings with suspected falsehood have increased after the reforms of LO 10/2022 and LO 4/2023, which have expanded the typical catalog under the express consent principle. Organic Law 1/2025 on Justice Service Efficiency has modified deadlines and procedural guarantees. Constitutional case-law on presumption of innocence and right to defense and Supreme Court doctrine on the three requirements of the Non-Jurisdictional Plenary Agreement of 28 September 1999 configure a demanding protective framework that defense must rigorously activate. At Alonso Sala, our criminal lawyers specialized in defense against false sexual assault accusations coordinate multidisciplinary teams with forensic psychologists, computer experts, family law specialists (when the accusation is instrumentalized in custody disputes) and experts in State liability. The intervention must be immediate: every hour without digital evidence preservation is a potentially lost evidentiary path; every premature statement by the investigated may compromise the defensive strategy. After acquittal, we articulate the counter-actions of Art. 456 CP and the civil claim for moral damages, as well as State liability (Art. 294 Organic Law of the Judiciary) if there was undue pretrial detention.
