You can't catch a Gardevoir in Pokemon Emerald. To obtain one you can catch a rare Ralts on Route 102 and evolve in into a Krilia, and then a Gardevoir.
You get Gardevoir by evolving Ralts to first Kirlia at lvl 20 and it will evolve to Gardevoir at lvl 30
You can catch a Kirlia and evolve it into Gardevoir at Lv. 30.
Gardevoir isn't in Platinum as far as I know.

There is a cameraman-and-reporter duo wanting to fight you in a Pokemon Center, and the reporter has a Gardevoir in Level mid-50's.
no it is not.
Kirlia evolves in lvl 30 in a Gardevoir or when it is a male and you use a Dawn Stone it evolves in a Gallade.
no because gallad is a fourth gen Pokemon meaning its only exclusive to diamond, pearl, platinum and heartgold and soulsilver. Also theres no dawn stone in sapphire which allows kirlia to evolve to gallad. Gardevoir doesn't evolve to gallad kirlia does.
