PART 4 - THE RACE - (B)45 to (B)59

57. Assisting another horse in the race

57.1 A Rider must not

57.1.1 make a manoeuvre in a race in the interests of another horse in Common Ownership or under common control or from the same stable or team, whether or not such a manoeuvre causes interference or causes his horse to fail to achieve its best possible placing, or
57.1.2 contravene any provision of this Part with the intention or with the consequence of giving advantage to another horse in Common Ownership or under common control or from the same stable or team.

57.2 Nothing in Paragraph 57.1 prohibits pure pacemaking as such.
57.3 Where a Rider is found to have contravened the prohibition in Paragraph 57.1, the Trainer of the horse shall also be taken to have contravened a requirement imposed on him by this Rule.
57.4 The Stewards may decide not to take Disciplinary Action against a Trainer under Paragraph 57.3 if the Trainer satisfies them that he instructed his Rider to treat every other horse in the race without any favour, however the race developed, and that the Rider acted regardless of such instructions.
57.5 Common ownership means that the horses in question share one or more owners in common and common control shall be similarly construed.
