Statement I:
"Rights express a certain kind of relationship between two parties i.e., the right holder and the right observer."
This statement is correct. Rights do indeed establish a relationship between the right holder (the person who has the right) and the right observer (those who have a duty to respect or uphold that right). For example, if someone has a right to free speech, others (including individuals, organizations, and the state) have a duty to respect that right by not infringing upon it.
Statement II:
"The concept of Positive Right entails non-interference from State and society at large."
This statement is incorrect. Positive rights are those that require active provision or intervention from the state or society. They entail entitlements to certain goods or services, such as the right to education, healthcare, or social security. Positive rights require the state to take action to ensure that these rights are fulfilled. In contrast, negative rights entail non-interference and require others, including the state, to refrain from certain actions, such as the right to freedom of speech or the right to privacy.
