LETTER OF INSTRUCTION NO. 10
TO: THE Postmaster General
In view of the present national emergency which has been brought about by the activities of those who are actively engaged in a criminal conspiracy to seize political and state power in the Philippines, and to take over the Government by force and violence the extent of which has now assumed the proportion of an actual war against our people and their legitimate Government, and pursuant to Proclamation No. 1081, dated September 21, 1972, and in my capacity as commander-in-chief of all the armed forces of the Philippines and in order to prevent the use of the mails for propaganda purposes against the government and its duly constituted authorities or for any purpose that tends to undermine the faith and confidence of the people in our Government and aggravate the present national emergency, you are hereby ordered to adopt measures of effectively controlling the use of the mails, including censorship.
Done in the City of Manila, this 26th day of September, in the year of our Lord, nineteen hundred and seventy two.
(Sgd.) FERDINAND E. MARCOS
