Hello, I believe there is an error when trying to download the questions:
from datasets import load_dataset
datasets = load_dataset("maastrichtlawtech/bsard", "questions")
Generates the following error:
{
"name": "DatasetGenerationError",
"message": "An error occurred while generating the dataset",
"stack": "---------------------------------------------------------------------------

The above exception was the direct cause of the following exception:

The problem should be fixed now, thanks for pointing it out!
