If you are doing prefs you don’t need to read this. I wrote this down mainly for my own benefit, to ensure consistency between rounds that involve ethics challenges.
If the Tabroom tells me to do something, it is not up for debate. I will do that thing. The rest is what I will do if left to my own devices.
Evidence ethics (out of context? straw-person? lied about quals? cut in middle of paragraph?) should be debated out like any other theory argument. Alternative remedies short of an automatic loss could be more responsive or proportional to the harm: scratching the argument AND evidence, scratching only the evidence and treating the argument as if it is made analytically, assuming an author is absolutely unqualified, requiring the team to produce the full text of articles in question, requiring the violating team to establish a paper trail authenticating other important evidence and presuming unauthenticated evidence to be fabricated, requiring a team to produce the full text of every article in the debate and presuming unauthenticated evidence to be fabricated, reducing speaker points, informing the team's coaches after the fact. They MAY be a reason to reject the team, but I will not treat them as such by default.
Clipping - claiming you read words from evidence that you did not read - is different, and a voting issue. It is a form of dishonesty that irreparably distorts teams' speech times, which affects every other issue in the debate, and which opponents are uniquely poorly positioned to police. If you are inexperienced or appear to have clipped by mistake, I will be lenient. Otherwise, it is non-negotiable.
On stopping the debate early:
Being racist, sexist, violent, etc. in a way that is immediately and obviously hazardous to someone in the debate = L and 0. My role as educator outweighs my role as any form of disciplinarian, so I will err on the side of letting stuff play out - i.e. if someone used gendered language and that gets brought up I will probably let the round happen and correct any ignorance after the fact. This ends when it begins to threaten the safety of round participants. You should give this line a wide berth.
