basis ____ [T]he police department is merely one very small part of this [sic] responsibility and he operates the police department through his interaction with the police chief. The police chief runs the department.
Relating to the Mayor’s testimony are several statements in our en bane opinion in Bennett v. City of Slidell, supra, 728 F.2d at 769. We said:
[C]ulpable policy is attributable to the governing body of the city where the policy was made by an official to whom the governing body had given policymak-ing authority____
The governing body retains the prerogative of the purse and the final legal control by which it may limit or revoke the authority of the official. The relinquishment of policymaking and supervision by the governing body is much more likely to exist, and be necessary, as the size and complexity of the government increases.
In Bennett we also said that the governing body may:
impliedly acknowledge that the agent or board acts in lieu of the governing body to set goals and to structure and design the area of the delegated responsibility, subject only to the power of the governing body to control finances and to discharge or curtail the authority of the agent or board. Ibid.
Affirmance on the merits in this case, therefore, could well be justified on the sole ground that the Chief of Police was the policymaker by delegation because of the size and complexity of the government of Houston, as Mayor Hofheinz described.
We in dissent do not, however, rest the decision solely on the ground that the Chief of Police was the policymaker. We insist that the court correctly charged the jury that the evidence had to establish “that there existed a regular pattern of such conduct so that it may be inferred that the City of Houston, through its high ranking officials, implicitly authorized or approved such conduct ... ‘[H]igh ranking officials’ means the mayor, city council, the police chief or some similarly ranked official whose acts may fairly be said to represent official policy.” This instruction reflects the law accurately and is in full accord with our decision in Bennett.
As the per curiam opinion for the Court points out, the Court has now unanimously agreed upon a formulation to govern the imposition of municipal liability. It provides:
A municipality is liable under § 1983 for a deprivation of rights protected by the Constitution or federal laws that is inflicted pursuant to official policy.
Official policy is:
1. A policy statement, ordinance, regulation, or decision that is officially adopted and promulgated by the municipality’s lawmaking officers or by an official to whom the lawmakers have delegated policy-making authority; or
2. A persistent, widespread practice of city officials or employees, which, although not authorized by officially adopted and promulgated policy, is so common and well settled as to constitute a custom that fairly represents municipal policy. Actual or constructive knowledge of such custom must be attributable to the governing body of the municipality or to an official to whom that body had delegated policy-making authority.
Actions of officers or employees of a municipality do not render the municipality liable under § 1983 unless they execute official policy as above defined.
Further, the majority per curiam opinion sets out at greater length the critical instruction to the jury which was given in this case.
A careful reading of our recently adopted formulation with the entire instruction to the jury reveals a remarkable compliance at that earlier time with the law as we now state it. As developed in this opinion in the next part, we do have here “a persistent, widespread practice of city officials or employees” which is so common
