Courts in Nigeria have remained shut, following a call by the Nigerian Bar Association (NBA) for a boycott to protest over last month's elections.
Emeka Obegolu says the elections were not run properly
A team of lawyers was seen going from court to court trying to ensure compliance with the boycott order.
The strike was effective in the capital, Abuja, as court rooms were kept shut during business hours.
"The boycott is symbolic; to show the masses of Nigeria that we share their frustrations," an NBA leader said.
"By our action, we are saying that elections were not properly conducted in Nigeria in 2007," Emeka Obegolu told the BBC News website in Abuja.
A similar strike called yesterday by civil society groups was not as successful as most Nigerians ignored it and went about their businesses.
But another strike is being planned by the central labour union to coincide with the 29 May inauguration of the governing party's Umaru Yar'Adua on 29 May.
Mr Yar'Adua won by a landslide, the Independent National Electoral Commission (Inec) says.
The results were rejected by the opposition parties, whose attempts to start mass protests were defeated by the police.
Local election monitors condemned the polls as a "charade."
Both the umbrella blue collar union, the Nigeria Labour Congress (NLC) and its white collar counterpart, the Trade Union Congress have called on their members to stay at home and hold neighbourhood rallies on 28 and 29 May.
