Notes

  1. It has been suggested that the ball might sell for something in excess of $1,000,000.

  2. The Giants’ website contains a page which shows where each of Bonds’ home runs landed in 2001. This page was introduced into evidence and is part of the record. It shows that most of the balls are clustered in the arcade area.

  3. Ted Kobayashi, a defense expert, testified that there was insufficient reaction time for the crowd to descend on Mr. Popov. This opinion is completely unconvincing. It is premised on the assumption that people did not begin to react until the ball hit Mr. Popov’s glove. A number of witnesses testified that they began reacting while the ball was in the air. People rushed to the area where they thought the ball would land. If people were unable to anticipate where a ball will land while it is still in the air, no outfielder would ever catch a ball unless it was hit directly to him or her. Moreover, the tape itself shows people descending on Mr. Popov even as he was attempting to catch the ball.

  4. Because the probability of truth does not favor the testimony of any of these witnesses in other particulars, their entire testimony is rejected. BAJI 2.22 This finding does not apply to Mr. Hayashi.

  5. Plaintiff argues that the Keppel tape shows Mr. Hayashi biting the leg of Brian Shepard. The tape does not support such a conclusion. The testimony which suggests that a bite occurred is equally unconvincing. In addition, there is insufficient evidence that Mr. Hayashi assaulted or attempted to take the ball away from Mr. Popov.

  6. Defense counsel has attempted to characterize this encounter as one in which Mr. Popov congratulates Mr. Hayashi for getting the ball and offers him a high five. This is an argument that only a true advocate could embrace.

  7. Testimony was also received about events which occurred after baseball officials escorted Mr. Hayashi to a secure area. This evidence was admitted to allow counsel to explore the possibility that Major League Baseball retained constructive possession of the ball after it landed in the stands and later gifted it to Mr. Hayashi. Defense counsel has properly abandoned this theory. There is no evidence to support it.

    The discussion was held during an official session of the court convened at The University of California, Hastings College of the Law. The session was attended by a number of students and professors including one first year property law class which used this case as vehicle to understand the law of possession.

  27. The degree of control necessary to establish possession varies from circumstance to circumstance. “The law . . . does not always require that one who discovers lost or abandoned property must actually have it in hand before he is vested with a legally protected interest. The law protects not only the title acquired by one who finds lost or abandoned property but also the right of the person who discovers such property, and is actively and ably engaged in reducing it to possession, to complete this process without interference from another. The courts have recognized that in order to acquire a legally cognizable interest in lost or abandoned property a finder need not always have manual possession of the thing. Rather, a finder may be protected by taking such constructive possession of the property as its nature and situation permit.” Treasure Salvors Inc. v. The Unidentified Wrecked and Abandoned Sailing Vessel (1981)640 F.2d 560, 571 (emphasis added).

  34. Professor Gray has suggested that the way to deal with this problem is to demand that Mr. Popov sue the people who assaulted him. This suggestion is unworkable for a number of reasons. First, it was an attack by a large group of people. It is impossible to separate out the people who were acting unlawfully from the people who were involuntarily pulled into the mix. Second, in order to prove damages related to the loss of the ball, Mr. Popov would have to prove that but for the actions of the crowd he would have achieved possession of the ball. As noted earlier, this is impossible.

  35. There are a number of ways courts can enforce the rule of law. Major League Baseball, as well as each individual team has a duty to provide security against foreseeable violence in the stands. The failure to provide that security, or worse, the tacit acceptance of some level of violence, will inevitably lead to lawsuits against the teams and the parent organization.

  36. The court is indebted to Professor Jan Stiglitz of California Western School of Law for his valuable insights and suggestions on this issue.
