Explanation:

The rule against perpetuity (Section 14 of the Transfer of Property Act, 1882) prevents property from being tied up indefinitely. While personal covenants (which do not create an interest in property) are generally outside the scope of the rule, pre-emption rights, especially those that are personal or limited in time, are often considered an exception or not subject to the rule against perpetuity. Permanent transfers for gift would generally be subject to the rule.
