In a bowl mix together pomegranate juice, salt, garlic, bay leaves, and peppercorns. Mix well until the salt is diluted
Place chicken pieces in a plastic bag, then pour marinade over them. Close the bag and gently move the pieces around so that the marinade covers all the pieces and they all lay flat
Let rest in the refrigerator overnight. Flip the bag at least once.
Remove chicken pieces from the bag and place on a paper towel. Allow to come to room temperature.
Spray the skin side of the chicken with cooking spray and place on the grill. Spray the opposite side, close the lid and grill on low for 10 minutes.
Flip the chicken and continue to grill for another 15 minutes or so, or until the chicken is fully cooked and the internal temperature is 160 degrees.
