arXiv:2606.07613v1 Announce Type: cross Abstract: Visual evidence has long been treated as a reliable form of legal proof, but advances in artificial intelligence (AI) are undermining that assumption. This article asks how well humans and frontier multimodal large language models (MLLMs) can distinguish authentic evidentiary photographs from AI-generated counterparts in the object-centric scenarios typical of civil disputes. We built Synthetic Legal Evidence Detection (SLED-1400), a dataset of 200 authentic evidence images paired with 1,200 synthetic counterparts produced by six contemporary t
Advances in generative AI, particularly multimodal large language models, have reached a point where synthetic media can convincingly mimic authentic visual evidence, prompting immediate concern regarding their legal implications.
This development directly undermines the long-standing reliability of visual evidence in legal proceedings, introducing significant challenges for truth determination and judicial integrity.
The judicial system, law enforcement, and forensic science must now rapidly adapt to a post-truth environment where evidentiary photographs can no longer be presumed authentic, requiring new verification methodologies and legal frameworks.

The necessity for sophisticated AI-powered detection tools will become paramount in every legal context involving visual evidence.
Legal standards for admissibility of visual evidence will undergo significant revisions, likely requiring provenance tracking and digital watermarking.
Public trust in photographic and video evidence, even outside legal contexts, could erode, leading to increased skepticism about digital media content overall.
