League Rules:
"Building a second race using Protoss Dark Archon's Mind Control ability is prohibited in league matches.
Starting construction of a Hatchery or a Command Center as Protoss is considered an immediate forfeit.
Use of Mind Control on other units or even worker units for purposes other than building a second race is permissible."
After reviewing the replay, your opponent never used Mind Control to build a Hatchery at any point during the match. Mind Control was only used on your units, which is explicitly permitted under the rules.
As no rule violation occurred, the result stands.
