This is odd; this is supposed to be public information, isn't it? I suspect it's run into bureaucratic empire-defending rather than a nefarious scheme to conceal cases.
Relatedly, there's an extremely good online archive of important cases in the past, but because they disallow crawlers in robots.txt: https://www.bailii.org/robots.txt not many people know about it. Personally I would prefer if all reporting on legal cases linked to the official transcript, but seemingly none of the parties involved finds it in their interest to make that work.
bureaucratic empire-defending is nefarious.
It is public information. The private company whose database is being deleted processed the public information into an easier to search and consume dataset
