Perhaps you should try some spelling variations:
"ley 1530 de 2012" » "ley 1537 de 2012", "ley 130 de 2012", "ley 1930 de 2012", "ley 1330 de 2012", "ley 1500 de 2012", "ley 153 de 2012", "ley 1530 de 2015"
"ley 1530 de 2016" » "ley 1537 de 2016", "ley 130 de 2016", "ley 1930 de 2016", "ley 1330 de 2016", "ley 1500 de 2016", "ley 153 de 2016", "ley 1530 de 2015"
ley 1508 » ley 1503, ley 1098, ley 1448
ley 1581 » ley 1341, ley 1480
ley 1563 » ley 1564, ley 1562, ley 1761

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1530 de 2012") OR ("ley 1530 de 2016"))) or ("((((((ley 1508) or (ley 1581))) or (ley 100))) or (ley 1563)) de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1530 de 2012") OR ("ley 1530 de 2016"))) OR ("((((((ley 1508) or (ley 1581))) or (ley 100))) or (ley 1563)) de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1530 de 2012\") OR (\"ley 1530 de 2016\"))) or (\"((((((ley 1508) or (ley 1581))) or (ley 100))) or (ley 1563)) de 2012\"))".
• Removing quotes may allow a broader search: (((( ley 1530 de 2012 ) OR ( ley 1530 de 2016 ))) or ( ((((((ley 1508) or (ley 1581))) or (ley 100))) or (ley 1563)) de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1530 de 2012") OR ("ley 1530 de 2016"))) or ("((((((ley 1508) or (ley 1581))) or (ley 100))) or (ley 1563)) de 2012"))*.
