I thank the Court for giving me a light sentence. If I may ask, exactly when will I be able to vote again? I'd like to avoid making this same mistake again.
Three weeks from the end of your original sentence OR if there is an election on going in that period which you would have been eligible to vote in (had you not erred) at the conclusion of voting for that/those election(s)...whichever comes last.
As to not allow a scenario to allow your sentence to stretch into perpetuity, the "added" time will only count from the first eligible election that occurs during your sentence but extends beyond it.
So say on the final week of your added suspension an election (which you could have otherwise voted in, say for president), your suspension will not end until the general voting booth for that first election closes. If say an eligible at large seat opens up a few days after (and its booth stays open a day or two longer) you can vote in that election on the days after your sentence is served.
