After reviewing in detail the scraper and the source from which the opinions are obtained, it is not possible to implement the backscraper at the moment since there is no way to filter the opinions by filling date, only the latest published opinions can be obtained

For reference, the link to "Montana Court Opinions" in this page https://courts.mt.gov/Library/mr/ is not working as of now.

This site provides copies of opinions and briefs dating back to the 1980s.

I checked the "Montana Court Opinions" on this page again https://courts.mt.gov/Library/mr/ and it still doesn't work.

I emailed the court today see if

http://searchcourts.mt.gov and https://courts.mt.gov/Library/mr/

are permanently down or perhaps they will be recovered. We should wait to hear back before we move into a time sucking process. @Luis-manzur

this seems impossible after discussion with the law librarians.

this was need to patch the gaps from error pages that were deleted; but we have the case names, dates and URLs logged here; so we could implement extract_from_text to get the missing docket number, and that way get the minimal information we need to create the objects needed

Only the Daily Orders page remains: https://juddocumentservice.mt.gov/getDailyOrders, and this one too: https://juddocumentservice.mt.gov/

This last one doesn't seem to be working correctly, none of the filters are returning results. I'll try again in a few days, maybe it can be used to backscrape the site.
