The senior Vulcan doctor at an interspecies medical conference who discovers that T'Pol has Pa'nar Syndrome and seeks to have her removed from her post because of its link to mind melds.
Dr Oratt appears in the Enterprise episode Stigma, set in 2152. He leads the Vulcan delegation at the Interspecies Medical Exchange conference on Dekendi III, which Phlox attends.
When Phlox makes discreet inquiries about Pa'nar Syndrome, Oratt becomes suspicious and obtains proof that T'Pol carries it. Vulcan authorities regard the disease as a mark of the despised minority who practise mind melds, and refuse to share research on it.
Oratt convenes a hearing to recall T'Pol. She will not defend herself by saying the meld was forced on her, since that would endorse the prejudice. His colleague Yuris tells the truth instead, and Oratt is obliged to let her remain aboard Enterprise.
