The Tate Gallery case concerns the issue of businesses overlooking private residences, which, it was successfully argued in this case, can cause a nuisance to local residents.
This extreme case concerns the Tate's viewing platform, which opened in 2016. The platform attracts millions of visitors each year, and from the platform, you can look directly into the opposite flats with glass walls.
The case was brought by the owners of these flats, who were subjected to visitors on the platform waving at them, taking photos and videos, and then posting them on social media.
These residents described the experience as if they were living in a "goldfish bowl".
