1.  For the purpose of this Chapter, the Parties reaffirm their right to regulate within their territories to achieve legitimate policy objectives, such as the protection of public health, safety, the environment or public morals, social or consumer protection or the promotion and protection of cultural diversity.  2.  For greater certainty, the mere fact that a Party regulates, including through a modification to its laws, in a manner which negatively affects an investment or interferes with an investor’s expectations, including its expectations of profits, does not amount to a breach of an obligation under this Section.   3.  For greater certainty, a Party’s decision not to issue, renew or maintain a subsidy:   (a) in the absence of any specific commitment under law or contract to issue, renew, or maintain that subsidy; or   (b) in accordance with any terms or conditions attached to the issuance, renewal or maintenance of the subsidy,   does not constitute a breach of the provisions of this Section.  4.  For greater certainty, nothing in this Section shall be construed as preventing a Party from discontinuing the granting of a subsidy or requesting its reimbursement where such measure is necessary in order to comply with international obligations between the Parties or has been ordered by a competent court, administrative tribunal or other competent authority, or requiring that Party to compensate the investor therefor.
