Now, I don't practice law in SC. MOreover, as U.C. goes by state law, I can only give you general impressions of how it might be handled.
Until a case reaches the appellate stage in front of a court, a U.C. case record is "open" for additional information and submissions. So, either side can add information to assist in determining eligibility, including your employer "adding" the information that you were going to be terminated for cause. Now, just because they can add it doesn't mean it's appropriate for evaluating your case. You do have the option of fighting the decision (if you still are within your timeframe for appeal) and argue why they did not produce this information in the very begining and that the reason is a pretext, a false reason created to dispute your benefits. So, I'd suggest you speak to a lawyer to see if you can appeal this determination. Best of luck!
