Criminal Lawyers in Child Pornography Possession

The offence of possession of child pornography for personal use (Art. 189.5 CP) sanctions with 3 months to 1 year of prison or a fine of 6 months to 2 years those who acquire or possess pornographic material in whose elaboration minors or persons with disabilities have been used. The protected legal interest is the sexual indemnity of minors in its transversal dimension: the criminalization of mere demand for material seeks to close the chain of child sexual exploitation by reducing the economic incentive for its production. The provision, introduced by LO 15/2003 and reformed by LO 1/2015, complies with the Lanzarote Convention and Directive 2011/93/EU. Its elements are effective possession of the material, knowledge of its illicit nature and the will to possess it, which allows the defence to contest automatic downloads, browser cache files without deliberate conservation and files received involuntarily.

The commissive modalities and technical scenarios are diverse. Conscious and organised possession implies deliberate storage in personal folders, renaming files, organization by themes or labels; it constitutes the most clearly reproachable typical modality. Possession in cloud storage systems (Dropbox, Google Drive, OneDrive, MEGA) with automatic synchronization to personal devices equally integrates the type, but raises evidentiary questions about effective account ownership. Files in browser temporary cache (cookies, temporary files, thumbnails) raise jurisprudential debate: the defence argues that files found exclusively in cache, without organisation or deliberate storage, do not by themselves prove typical possession. Automatic unsolicited downloads through P2P programs, received in WhatsApp/Telegram groups, or introduced by third parties with device access, exclude intent when absence of knowledge is proven.

The penalties and accessory consequences, although less than in production or distribution modalities, are significant. The alternative principal penalty is 3 months to 1 year of prison or a fine of 6 months to 2 years. When the imposed sentence does not exceed 2 years and the accused has no prior records, Art. 80 CP allows sentence suspension avoiding actual imprisonment, although this does not exempt from accessory consequences. The mandatory registration in the Central Sex Offenders Registry (RD 1110/2015) for periods up to 30 years, the disqualification to work with minors in any sphere (education, pediatric healthcare, sports, entertainment, school transport), supervised release of 1 to 5 years where prison is imposed, which the court may waive for a single offence by a first-time offender (Art. 192.1 CP), and civil liability for moral damages are consequences to be anticipated. The forfeiture of electronic devices seized as instrument of the offence is ordered under Art. 127 CP.

Technical defence is built on four axes. First, the absence of intent in possession: the criminal type requires effective knowledge and will; when files come from automatic browser downloads, files stored in cache without deliberate conservation, unsolicited receipts in messaging groups, messages with automatic preview (WhatsApp, Telegram), or pop-ups during browsing, computer expert evidence can prove the absence of acquisition will. Second, the challenge of authorship attribution: in devices shared in households with multiple users, vulnerable or password-less wifi networks, unauthorized remote access, active malware that used the equipment without titular's knowledge, the in dubio pro reo principle operates when certain identification is not proven. Third, the challenge to the evidence due to chain of custody defects: absence of write blocker during initial cloning, discrepant hashes between original and copy, documentary defects in device traceability, undermine the reliability of the evidence and allow it to be challenged. Fourth, the nullity of home search or content examination: judicial authorization for home search does not automatically cover the examination of content of computers found (Art. 588 sexies a Criminal Procedure Act); content examination requires specific authorization.

In current forensic practice, possession investigations mostly arise from automatic provider alerts (Microsoft, Google, Meta, Apple) through technologies like PhotoDNA and Content Safety API, which are transmitted to NCMEC and Spanish national authorities (BIT-National Police, GDT-Civil Guard). International operations coordinated by Europol and Interpol generate massive proceedings with hundreds of simultaneous investigated persons. Organic Law 8/2021 on integral protection of childhood, the Budapest Convention on Cybercrime, Organic Law 1/2025 on Justice Service Efficiency and constitutional case-law on electronic evidence configure a demanding procedural scenario. At Alonso Sala, our criminal lawyers specialized in child pornography possession coordinate multidisciplinary teams with forensic computer experts performing exhaustive forensic audits, identifying cache files versus deliberately stored files, detecting active malware on download dates, examining user session attribution, and articulating technical defences that can determine acquittal, sentence suspension when Art. 80 CP circumstances concur, and minimization of impact on the defendant's professional trajectory and record.
