@adunning: this should probably be included in the style-variant-builder repo?

From what I understand, Andrew is already working on it: https://forums.zotero.org/discussion/130498/oscola-march-2026#latest

I have been looking at this: I'm working on an embedded version of OSCOLA in MHRA and New Hart's Rules (as Bluebook is with APA and Chicago). I won't be able to work on it seriously until the summer, so in the meantime it's very helpful to have others establishing a baseline.

I have been looking at this: I'm working on an embedded version of OSCOLA in MHRA and New Hart's Rules (as Bluebook is with APA and Chicago). I won't be able to work on it seriously until the summer, so in the meantime it's very helpful to have others establishing a baseline.

This is interesting indeed - I am not sure however that MHRA or New Hart's Rules recommendations to use Oscola to cite legal texts will work so well with CSL given that a lot of what Oscola requires cannot be implemented in CSL at all because it requires checks of the content of the variable fields (cf Juris-M and CSL-M). I've been supporting an update of the biblatex OSCOLA package as well as making these edits, where the required logic is implemented, but as far as I understand it's not really possible in CSL, sadly.

In any case @adunning, I have made the changes in your comments! Thanks!
