Whether Acquiescence Constitutes the Principle of Estoppel in Territorial Dispute Cases: Case of Temple of Preah Vihear as an Example

Abstract

The principle of estoppel and acquiescence are widely applicated in territorial disputes. In some cases, acquiescence can lead to estoppel, but the specific criteria for its application still need further clarification. Otherwise, the abuse of estoppel followed by acquiescence might result in a violation of the sovereignty of other States. In this study, we focused on the case of Temple of Preah Vihear to gain a more extensive understanding about the prerequisites of that acquiescence constitutes estoppel in territorial disputes, and we concluded the basic conditions that acquiescence acts might lead to estopple through other relevant cases and literatures.
