I suspect the judgement ability with seal of righteousness active is incorrectly being affected by spell miss talents.
I first noticed this anecdotally in arenas, so I found a rogue willing to help me test with 2/2 Heightened Senses which reduces the rogue’s chance to be hit by 4% from ranged attacks and spells.
Wearing 166 hit rating (5.06%) I was able to reproduce misses against a human rogue (level 80s both of us and not night elf or blood elf since they have additional 2% miss racials) and using the default in game combat log filters, the misses show by checking under Message Types → Spells → Misses. There are filters for melee and ranged misses as well, neither of those filters show the judgement misses.
Per official patch notes, 3.2.0 in WOTLK: “Judgments: Some of these attacks were considered ranged and some melee. They are all now considered melee attacks that can’t be dodged, parried or blocked.”
I cannot find any official patch notes beyond patch 3.2.0 that reversed directions in regard to judgements and which hit type they use, therefore I am led to believe that it is a bug.
