In Civ5, is it possible to buy a courthouse?

Solution 1:

Once the resistance is over, you can buy the Courthouse for 600 gold, which is slightly more expensive than other buildings that cost 100 hammers.

Before the patch released on 15 December 2010 it was not possible to buy a courthouse

Solution 2:

No, you cannot buy courthouses, but you can use a great engineer to speed building up to 1 turn (confirmed last night).

Solution 3:

Also, if you have the spare money, you can buy Workshop, Windmill, etc to speed up production.

Solution 4:

As of the patch deployed on 12/15:

• Reduced production cost and maintenance for the Courthouse.
• Courthouse can now be purchased in a city (although it is expensive).
