1888年1月19日,英國就《英皇制誥》及《皇室訓令》兩份規管香港管治的憲制文件再作修訂,加入明文:新任港督履行職務前,須在高等法院法官與行政局成員見證下宣誓;此宣誓要求亦涵蓋其他須作宣誓的公職人員。
On 19 January 1888, Britain further amended the Letters Patent and Royal Instructions, the two constitutional documents governing Hong Kong, adding an express provision that the new Governor must take an oath before assuming office in the presence of a High Court judge and Executive Council members; this oath requirement also covered other public officers required to take an oath.
