Confusion and ambiguity emerged last night over the definition of political organisations. A source close to the Chief Executive-designate's office admitted political participation might be open to different interpretations. 'Some political parties have already said it's not fair to them because other groups can take part in elections in the form of functional groups and are therefore immune from the new requirement,' said the source. The proposals define political organisations as societies which - as their main objectives - directly participate in political activities relating to government institutions and comment on public affairs. Parties taking part in elections are considered political organisations. But organisations taking part in functional constituency polls are not included because their primary objective relates to their own professions, the consultative paper says. Another source said it was possible a group would be seen as a functional group if a member took part in functional polls, but a political organisation if a member joined geographical elections. Benedict Lai Ying-sie, principal Crown counsel in Mr Tung's office, said the definition was clear and strict. There were a number of safeguards against abuses of civil rights. The proposal also bars political organisations from ties with foreign countries. The definition of ties includes soliciting and accepting money - directly or indirectly - from 'aliens and foreign organisations' and affiliation with foreign political organisations. Foreign political organisations include foreign governments, political parties overseas and 'international political organisations'. The second source said no specific groups were intended in the category of international political organisations. Article 23 of the Basic Law bars political groups from forging ties with foreign political bodies, not individuals. Michael Suen said individuals had been included to plug the loophole of groups giving donations through individuals. He said: 'Of course, nobody will ask what passport you hold when you give donations to boxes placed by political parties in streets. Whether migrants in foreign countries are considered as 'aliens' will depend on how we define nationality in other laws.'
