You really do not understand:

1-The question is why the symbols must be removed from the infobox;

2-They MAY be still valid. What we have until now, and nobody can find more evidences, is that law of 1962; The last law that deals SPECIFICALLY with the topic is the one to be followed; It doesn´t matter if this law is from the time of Cleopatra. It doesn´t matter if it´s a colonial symbol.

3-There are many examples throughout history: New York city, Jakarta, São Paulo city, Rio de Janeiro city, and many other cities used their colonial symbols until a new law dealing with the subject was created. Some even maintained their colonial symbols, like New York and Rio. That´s a heraldry principle.

4-What we can do is to put a tag or something saying "MAYBE STILL IN USE". If there is no newer law dealing with the symbols of Dili, YES THEY ARE VALID NOWADAYS, as strange as it can be.

5-If they belong to the colonial times, why we have a photo of 1991 with Ramos Horta holding the flag of an occupied territory, that is struggling with invasion and doesn´t want to be a colony again?
