The CPS said there is "sufficient evidence" to prosecute Nicholas Jacobs over the 1985 murder of PC Keith Blakelock.
They added there was "insufficient evidence" prosecute five other suspects.
Alison Saunders, Chief Crown Prosecutor for CPS London, said:
Following a thorough investigation by the Metropolitan Police Service, we have decided that Nicholas Jacobs should be charged with the murder of PC Keith Blakelock during the disorder at Broadwater Farm in October 1985.
This decision was taken in accordance with the Code for Crown Prosecutors. We have concluded that there is sufficient evidence and it is in the public interest to prosecute.
We have also concluded that no further action should be taken against five other individuals suspected of taking part in the death of PC Blakelock as there is insufficient evidence to warrant a prosecution.
