CREATE TABLE table_203_303 (id DECIMAL, "tribunal" TEXT, "number of autos da fe" DECIMAL, "executions in persona" DECIMAL, "executions in effigie" DECIMAL, "penanced" DECIMAL, "total" DECIMAL)

what was the only tribunal to pronounce zero sentences ?
SELECT "tribunal" FROM table_203_303 WHERE "total" = 0
SELECT "tribunal" FROM "table_203_303" WHERE "total" = 0
