Thanks Shivam for reaching out!
The deadlines for the fallacy detection task are here: Touché at CLEF 2026 - Fallacy Detection
Specifically, the deadline for run submissions are May 21, 2026 (the other deadlines are mentioned there as well).
For the submission: please upload your runs here: https://www.tira.io/task-overview/fallacy-detection/
I think there are no requirements on the minimum paper length, there is a review process, but it is a positive review process. The paper template is CEUR-WS. Usually, papers are reviewed by organizers and people that are invited by the organizers, so if you want to review, please reach out, we would be happy 
The data is still in the final polishing stage, I hope that we can realease the data very soon.
Best regards,
Maik
