Final answer:
The conditions for violating the Establishment Clause through sect preference.
Step-by-step explanation:
The conditions that must be met for the Establishment Clause to be violated by sect preference are:
- The law must not have the primary effect of advancing or inhibiting religion.
- The law must have a legitimate secular purpose.
- The law must not result in an excessive entanglement of government and religion.
An example of a case related to the Establishment Clause is Lemon v. Kurtzman in which the Supreme Court established the 'Lemon Test' to determine whether a law violates the Establishment Clause.
