Germany 2018 – Oberlandesgericht Naumburg acquittal of ARIWA investigators
Court Decision
In Effect
February 21, 2018
Summary
On 21 February 2018, the Higher Regional Court (Oberlandesgericht) Naumburg in Saxony-Anhalt rejected the public prosecutor’s appeal on points of law (Revision), thereby confirming the acquittal of three Animal Rights Watch (ARIWA) investigators charged with criminal trespass (Hausfriedensbruch) in connection with an undercover investigation conducted in 2013 at the van Gennip Tierzuchtanlagen GmbH pig breeding facility in Saxony-Anhalt. The court upheld earlier acquittals from the District Court (Amtsgericht) Haldensleben (September 2016) and the Regional Court (Landgericht) on appeal. The ruling confirmed that, in the circumstances of this case, the investigators’ entry and covert recording at the pig breeding facility to document alleged violations of the German Animal Welfare Act did not constitute punishable trespass. The decision is binding within the jurisdiction of the Oberlandesgericht Naumburg and may be cited as persuasive authority in other German state jurisdictions. The criminal proceedings against van Gennip Tierzuchtanlagen GmbH for alleged animal welfare violations had been separately discontinued by the end of 2015 without a conviction of the facility operators.
Background Context
In 2013, ARIWA conducted an undercover investigation at van Gennip Tierzuchtanlagen GmbH, described in NGO sources as one of the largest pig breeding operations in Germany, and published video and photographic material documenting conditions that ARIWA characterised as serious violations of the Animal Welfare Act (Tierschutzgesetz). Criminal proceedings against the facility operators for alleged animal welfare violations were initiated following publication but discontinued by the end of 2015 without conviction. Three ARIWA investigators who had entered the premises and recorded covert footage were separately charged with criminal trespass and stood trial at the Amtsgericht Haldensleben in September 2016, where they were acquitted. The public prosecutor’s office filed a Revision (appeal on points of law) to the Higher Regional Court Naumburg challenging the legal assessment underpinning the acquittals. Later in 2018, the German Federal Court of Justice (Bundesgerichtshof) issued a decision in a separate case involving publication of undercover recordings from an organic egg farm by broadcaster MDR, ruling that such images could be published under certain conditions; this decision concerns publication and press freedom rather than trespass and is part of the broader jurisprudential context on undercover farm investigations.

Low
The Oberlandesgericht Naumburg issued its judgment on 21 February 2018, rejecting the public prosecutor’s Revision and leaving the Amtsgericht and Landgericht acquittals in place. The three ARIWA investigators were definitively acquitted of criminal trespass charges arising from their 2013 entry into the van Gennip pig breeding facility. The ruling confirmed that covert entry and recording at the facility, undertaken to document suspected animal welfare violations, did not result in criminal liability in the circumstances assessed by the court. No further ordinary legal remedy against the acquittal is reported in available sources. The ruling enables continued publication and use of the recorded material without a criminal conviction of the investigators. Animal Equality and other NGOs cited the decision as part of the legal context for continued undercover investigative work in German agricultural facilities. A subsequent Federal Court of Justice decision in 2018, in a separate case involving MDR broadcast footage from an organic egg farm, addressed the publication of undercover investigation material under press freedom provisions; that ruling is a distinct development in the broader jurisprudential landscape.
Anticipated Effects
If courts in other German state jurisdictions apply the Oberlandesgericht Naumburg’s reasoning analogously in future trespass cases involving undercover investigative entry into agricultural facilities, the legal risk for investigators documenting alleged animal welfare violations may be reduced in those jurisdictions.
If investigators and media organisations treat the ruling as supportive of covert documentation in agricultural operations, the volume of visual material from pig breeding and other livestock facilities could increase, which would conditionally increase exposure of housing and handling conditions within German animal agriculture.
The acquittal itself does not modify statutory standards for treatment, housing, or slaughter of animals; any effects on system practices or animal numbers would be indirect and conditional on subsequent investigative activity, media coverage, and regulatory or enforcement responses.
Significance Rationale
Assigned Neutral / Administrative (impact direction) because the ruling resolves the legal status of investigators’ conduct in one trespass case without directly changing the number of pigs in German production systems, closing or opening facilities, or altering husbandry or slaughter standards. The pig breeding and production system at van Gennip and nationally continued at comparable scale following the ruling. No documented evidence links the acquittal to changes in animal numbers, facility operations, or industry-level practices.
Assigned Alters Legal Basis (impact type) because the ruling clarifies how criminal trespass law applies to covert investigative entry into agricultural facilities undertaken to document alleged Animal Welfare Act violations — the same type of legal basis clarification as the BVerwG male chick killing ruling (2019), which confirmed legal interpretation without itself producing a scale change.
Assigned Low significance because the ruling directly affects three investigators and one facility in Saxony-Anhalt. Its broader jurisprudential reach is regional within the Oberlandesgericht Naumburg’s jurisdiction and persuasive elsewhere in Germany, but no empirically documented change in investigative practices, prosecution rates, or facility conditions at national scale has been identified in sources consulted.
Impact direction is Neutral / Administrative; the trajectory sentence is not applicable.

Key Actors
The Oberlandesgericht (Higher Regional Court) Naumburg, Saxony-Anhalt, issued the judgment on 21 February 2018. The three ARIWA investigators were the acquitted defendants. Animal Rights Watch (ARIWA), a German animal rights organisation, organised the 2013 undercover investigation and publicly released the footage. Van Gennip Tierzuchtanlagen GmbH, a pig breeding business in Saxony-Anhalt, was the subject of the investigation; criminal proceedings against its operators for alleged animal welfare violations were discontinued by end of 2015. The public prosecutor’s office in Saxony-Anhalt pursued the Revision that the Oberlandesgericht rejected. Animal Equality (international NGO) reported on the ruling in English and situated it in the context of ongoing undercover investigation activities in Germany.
Editorial Correction Notice
Affected animals: No Animals CPT records are assigned. The ruling acts on investigative access law and the legal status of the investigators’ conduct — it does not directly regulate the treatment, numbers, or conditions of any animal species. Pigs are the species documented in the underlying investigation, but the ruling does not directly affect pigs or pig farming practices. This follows the same reasoning as the Arbeitsschutzkontrollgesetz (labour law) record: when a Court Decision acts one layer removed from animals rather than directly regulating their treatment, species assignment is not warranted.
Affected practices: No Practices CPT records are assigned. The practices documented in the 2013 investigation — Intensive Confinement, Physical Restraint, Premature Weaning and Separation — are background conditions of the investigated facility, not practices directly regulated by this Court Decision. The ruling regulates investigative access; it does not regulate the practices themselves.
Key industries: No key_industries assignment. The ruling acts on investigative access law rather than directly on an industry. Assigning the Meat industry would imply a direct regulatory relationship between the ruling and pig farming that does not exist.
Primary sources: No full official written judgment from the Oberlandesgericht Naumburg has been accessed in sources consulted. Available information relies on NGO summaries from Animal Equality and ARIWA. The specific Staatsanwaltschaft office, exact Landgericht location, and case file numbers (Aktenzeichen) are not provided in available sources. A direct official court document or published judgment would strengthen this record before it moves to Review.
Related development: A 2018 Federal Court of Justice (Bundesgerichtshof) decision in a separate case involving MDR broadcast footage from an organic egg farm is referenced in available sources as part of the broader jurisprudential context. That decision concerns publication and press freedom rather than trespass and may warrant a separate Development record if further research confirms it as a discrete datable development meeting the evidence threshold.
