16.If the Scottish Ministers withdraw from a marine policy statement, or a marine policy statement is withdrawn, then the validity or effect of a national marine plan or regional marine plan is unaffected. The construction of any national or regional marine plan is unaffected in the period between a marine policy statement being withdrawn and a new statement coming into effect. The withdrawal of a national marine plan by Scottish Ministers does not affect the validity of a regional marine plan, nor the construction of any regional marine plan until a new national marine plan is in effect.
