The SEARCH tab is used to launch caselaw searches by means of quoted rules. Enter the law or section in the filter option ‘quoted rules’. As you write, the options found by the system for those parameters will open. From the search engine you can apply several sections from the same regulation or others at the same time.
Then, you can click on the search button and the system will retrieve all judgments that apply or quote the said legal provision.
In the filter options placed at the right side of the screen, you will find the legal provisions applied to the search, which can be modified from the editable box therein.
