Aulic Council
When Clara's brother Julius inherited Wolfenbüttel in 1568, he also took possession of Westerhof. Clara sued him before the Aulic Council, but in 1580, Philip confirmed Juilius's ownership. Clara then sued Julius over the inheritance of her sister Margaret. The Aulic Council created an imperial commission to look into the matter. Julius, however, rejected the commission and filed a complaint at the Diet of Augsburg of 1582 about the illegal practices of his sister.
