* Solemn Judgment's effect: Solemn Judgment negates the activation of a Spell/Trap card or effect that Special Summons a monster and destroys it.
* Gorz's effect: Gorz the Emissary of Darkness is Special Summoned by its own effect, which is triggered when your opponent Special Summons a monster(s). This effect is not a Spell/Trap card or effect.
* Non-inherent Special Summon: Gorz's effect is considered a non-inherent Special Summon because it is not a part of its own summoning condition.
Therefore, Solemn Judgment will not work against Gorz the Emissary of Darkness because it doesn't negate the activation of a Spell/Trap card or effect.
Important Note: While Solemn Judgment won't stop Gorz's summoning, other cards like "Solemn Strike" or "Solemn Warning" can negate the Special Summon of Gorz itself.
