flags are placed in a straight line, the rightmost flag (leftmost to the observer facing the flag) is the Indian flag, followed by other national flags in alphabetical order. When placed in a circle, the Indian flag is the first point and is followed by other flags alphabetically. In such placement, all other flags should be of approximately the same size with no other flag being larger than the Indian flag. Each national flag should also be flown from its own pole and no flag should be placed higher than another. In addition to being the first flag, the Indian flag may also be placed within the row or circle alphabetically. When placed on crossed poles, the Indian flag should be in front of the other flag, and to the right (observer's left) of the other flag. The only exception to the preceding rule is when it is flown along with the flag of the United Nations, which may be placed to the right of the Indian flag. When the Indian flag is displayed with non-national flags, including corporate flags and advertising banners, the rules state that if the flags are on separate staffs, the flag of India should be in the middle, or the furthest left from the viewpoint of the onlookers, or at least one flag's breadth higher than the other flags in the group. Its flagpole must be in front of the other poles in the group, but if they are on the same staff, it must be the uppermost flag. If the flag is carried in procession with other flags, it must be at the head of the marching procession, or if carried with a row of flags in line abreast, it must be carried to the marching right of the procession. Half-mast The flag should be flown at half-mast as a sign of mourning. The decision to do so lies with the President of India, who also decides the period of such mourning. When the flag is to be flown at half mast, it must first be raised to the top of the mast and then slowly lowered. Only the Indian flag is flown half mast; all other flags remain at normal height. The flag is flown half-mast nationwide on the death of the President, Vice President or Prime Minister. It is flown half-mast in New Delhi and the state of origin for the Speaker
