§ 3037. Appeal. An appeal may be taken only from a judgment, or an
order determining the making of the contract or submission or the
failure to comply therewith. There shall be no appeal from an
intermediate order of the court or of a judge in an action under the
simplified procedure provisions, except with the permission of the trial
or appellate court, but such order or orders may be reviewed on the
appeal from a judgment entered under these provisions. A decision of the
trial judge on the facts shall be final if there is any substantial
evidence to support it.
