It is now settled law, that it is not every mistake in a judgment or decision that can warrant the reversal of a decision. To justify a reversal of a decision, the error complained of must be of such a nature to cause real miscarriage of justice. In the instant case, the fact that a breach was considered, even if erroneously, in appeal which does not concern the appellant, cannot be a basis for the appellant to complain.
