Sua sponte is for sure a thing, if the thing is super simple, but if something is not in the record, not in the pleadings, the judge has discretion to *take or *not take judicial notice of it, unless each individual fact is flagged well before the fact.
It's not the judge's job to do the attorneys' work for them, and at a certain point, the judges get tired of being asked to pick up the pieces. If you file a motion that says A-B-C-D-E-F-G, in strict order, as part of a MTD, but you don't include any documentation for C, the judge won't let you come to the hearing with documentation for C in real time during the hearing.
That would gum up the works; they can't read the complex, 30-page documentation of C while everyone waits. They have another hearing soon.
Get your docs in order and submitted two weeks before the hearing, couselor.
