Criminal Lawyers in Child Pornography

The offence of child pornography (Art. 189 CP) protects the legal interest of minors' sexual indemnity and, mediately, their dignity and integral development guaranteed in the UN Convention on the Rights of the Child (1989) and the Lanzarote Convention (Council of Europe 2007). The reform under LO 1/2015 radically expanded the typical scope, incorporating not only material using real minors but also realistic representations generated by computer, deepfakes and images produced by artificial intelligence staging minors or persons appearing to be in sexually explicit attitudes. Consolidated Supreme Court case-law and CJEU (case C-348/19) clarifies the contours of the type, distinguishing commissive modalities and requiring specific intent for all of them.

The Criminal Code structures three autonomous modalities with radically differentiated penalties. The production of pornographic material with real minors (Art. 189.1.a CP) is the most severely punished conduct, with 5 to 9 years' prison; when the aggravating factors of Art. 189.2 CP concur (minor under 16, prostitution situation, criminal organization, special degradation), the penalty can reach 9 years in upper half and require actual incarceration. Distribution, facilitation, dissemination or making available of child pornographic material (Art. 189.1.b CP) carries 1 to 5 years' prison; includes activities in P2P networks, forums, Telegram channels, shared cloud storage. Mere possession for personal use (Art. 189.5 CP) is punished with 3 months to 1 year of prison, or 6 months to 2 years' fine; although the penalty is the lowest, collateral consequences are devastating: registration in the Central Sex Offenders Registry for decades, disqualification to work with minors, device seizure.

The detection and prosecution mechanisms are highly technological. PhotoDNA, developed by Microsoft and adopted by Google, Facebook, Twitter and other providers, automatically scans file uploads and, through robust hashing, identifies known material catalogued by the NCMEC (National Center for Missing & Exploited Children). Alerts are transmitted to NCMEC, which redirects them to national authorities (in Spain, the BIT-Technological Investigation Brigade of the National Police and the GDT-Telematic Crime Group of the Civil Guard). Investigations develop through IP address tracking, requesting information from service providers (ISPs), international letters rogatory coordinated by Europol and Interpol, and undercover operations on forums and P2P networks. The digital chain of custody is a critical element: any defect in forensic cloning, use of write blockers, hash MD5/SHA256 verification or device sealing may determine evidentiary nullity.

Technical defense is built on four axes. First, the absence of intent in possession: the possession offence requires knowledge and will to possess; when files come from automatic browser downloads, cache-stored files, unsolicited receipts in Telegram/WhatsApp groups or pop-ups, computer expert evidence can prove the absence of acquisition will. Second, the incorrect identification of perpetrator: an IP address identifies a connection point —typically a router— and not a specific physical person; when the wifi network was vulnerable, there were several users in the dwelling, password was shared with neighbors or the router presented security failures, the in dubio pro reo principle operates. Third, the vulnerabilities of digital chain of custody: device manipulation without write blockers, absence of verification hash, sealing failures, breakage of documentary traceability, determine evidentiary nullity. Fourth, the challenge of police operation: entry and search must have motivated judicial authorization, legal assistance to the detained must be respected from the first moment, and line-ups and witness statements must adjust to procedural guarantees.

In current forensic practice, police operations on child pornography have reached massive dimensions: coordinated international operations with hundreds of simultaneous investigated, server interventions abroad through international judicial cooperation (EU Regulation 2018/1727 on Eurojust, MLA), application of the Budapest Convention on Cybercrime. Organic Law 8/2021 on integral protection of childhood and adolescence against violence has reinforced the protective framework and hardened penalties. Organic Law 1/2025 on Justice Service Efficiency and constitutional case-law on electronic evidence and Supreme Court doctrine on intent and typical attribution configure a demanding procedural scenario. At Alonso Sala, our criminal lawyers specialized in child pornography work with a multidisciplinary team of computer forensic experts, international judicial cooperation specialists and cybersecurity experts to audit the digital chain of custody, challenge evidence obtained in jurisdictions with lower standards, articulate defenses based on absence of intent, and build procedural strategies aimed at acquittal, sentence suspension when Art. 80 CP circumstances concur, and minimization of devastating accessory consequences (Central Sex Offenders Registry, professional disqualification).
