The averment of jurisdiction consists of a statement that the acts of the defendant are contrary to equity and good conscience and that the complainant has no relief except in a court of equity. This averment is absolutely without value. If the premises make out a cause for equitable relief this averment is unnecessary, and if no cause for relief has been shown, this clause cannot give equity jurisdiction.
