The attached documents also included a written agreement requiring Keota to provide management assistance and consulting services to Double Circle.

Ps also sought to impose liability against Keota by piercing the corporate veil. The court found Ps failed to produce any facts to show that Keota engaged in conduct separate from its duties as director or manager of Double Circle.

It also concluded there was insufficient evidence as a matter of law to pierce the corporate veil. Ps appealed.
