The 'Textuality Principle' Is a Principle of Interpretation Used by the EctHR

The 'textuality principle' is a principle of interpretation used by the EctHR - but what does it mean?

A) The court must have regard to all relevant written texts (i.e. the Convention, other relevant treaties and its own judgments) in reaching a decision.
B) The court must have regard to the ordinary meaning of the terms of the Convention in its context and in the light of its object and purpose.
C) The court must adopt a teleological approach in interpreting the text of the Convention.
D) The court must, in interpreting the Convention, treat the text as a 'living instrument'.
