Smith was involved in litigation in California. She lost her case in the trial court. She appealed to the California appellate court, arguing that the trial court judge had incorrectly excluded certain evidence. To support her argument, she cited rulings by the Supreme Court of North Dakota and the Supreme Court of Ohio.

Both the North Dakota and Ohio cases involved facts that were similar to those in Smith's case. Does the California court have to follow the decisions from North Dakota and Ohio? Support your answer.
