Each record gives the issuing body, number, date, topics, a one-sentence holding in our words, a practical step, whether it is still in force, the official link, an exact short quote and the date read. It is not the opinions' full text.251 records (status: P 249, S 2). Canonical page: https://probativegrowth.com/data/opinions/. API: https://probativegrowth.com/data/v1/opinions/index.json.
