According to the Mattel Official Rulebook, a Wild Draw 4 card may be played only if the player does not have a card in their hand that matches the colour of the card previously played. If you suspect a player has played this card illegally, you may challenge them. The challenged player must show their hand to the challenger. If the challenged player is found guilty, they must draw the 4 cards. However, if the challenged player is innocent, the challenger must draw the 4 cards plus an additional 2 cards, for a total of 6 cards.
