§ 70.25 Concurrent and consecutive terms of imprisonment.
  1.  Except  as  provided  in  subdivisions two, two-a and five of this
section, when multiple sentences of imprisonment are imposed on a person
at  the  same  time, or when a person who is subject to any undischarged
term of imprisonment imposed at a previous time by a court of this state
is  sentenced  to  an  additional  term of imprisonment, the sentence or
sentences  imposed  by  the  court  shall  run  either  concurrently  or
consecutively  with  respect  to each other and the undischarged term or
terms in such manner as the court directs at the time  of  sentence.  If
the  court does not specify the manner in which a sentence imposed by it
is to run, the sentence shall run as follows:
  *  (a) An indeterminate or determinate sentence shall run concurrently
with all other terms; and
* NB Effective until 2005/09/30
  *  (a) An indeterminate sentence shall run concurrently with all other
terms; and
* NB Effective 2005/09/30
  (b)  A  definite  sentence  shall  run  concurrently with any sentence
imposed at the same time and shall be consecutive to any other term.
  2.  When more than one sentence of imprisonment is imposed on a person
for two or more offenses committed through a single act or omission,  or
through  an  act  or  omission  which  in  itself constituted one of the
offenses and also was a material element of the  other,  the  sentences,
except  if  one  or more of such sentences is for a violation of section
270.20 of this chapter, must run concurrently.
  *  2-a.  When an indeterminate or determinate sentence of imprisonment
is imposed pursuant to section 70.04, 70.06, 70.08  or  70.10  and  such
person  is  subject  to  an  undischarged  indeterminate  or determinate
sentence of imprisonment imposed prior to the date on which the  present
crime   was   committed,  the  court  must  impose  a  sentence  to  run
consecutively with respect to such undischarged sentence.
* NB Effective until 2005/09/30
  *  2-a.  When  an  indeterminate  sentence  of imprisonment is imposed
pursuant to section 70.04, 70.06, 70.08 or  70.10  and  such  person  is
subject  to  an  undischarged  indeterminate  sentence  of  imprisonment
imposed prior to the date on which the present crime was committed,  the
court  must  impose a sentence to run consecutively with respect to such
undischarged sentence.
* NB Effective 2005/09/30
  *  2-b.  When  a  person  is  convicted  of  a  violent felony offense
committed after arraignment and while released on recognizance or  bail,
but  committed  prior  to the imposition of sentence on a pending felony
charge, and if an indeterminate or determinate sentence of  imprisonment
is  imposed  in  each  case,  such  sentences  shall  run consecutively.
Provided, however, that the court may, in the interest of justice, order
a  sentence  to  run  concurrently  in  a  situation  where  consecutive
sentences are required by this subdivision if it finds either mitigating
circumstances  that bear directly upon the manner in which the crime was
committed or, where the defendant was not the sole  participant  in  the
crime,  the  defendant's participation was relatively minor although not
so minor as to constitute a defense to the  prosecution.  The  defendant
and  the district attorney shall have an opportunity to present relevant
information to assist the court in making  this  determination  and  the
court  may,  in  its  discretion,  conduct a hearing with respect to any
issue bearing upon such determination.  If  the  court  determines  that
consecutive  sentences  should not be ordered, it shall make a statement
on  the  record  of  the  facts  and  circumstances  upon   which   such
determination is based.
* NB Effective until 2005/09/30
  *  2-b.  When  a  person  is  convicted  of  a  violent felony offense
committed after arraignment and while released on recognizance or  bail,
but  committed  prior  to the imposition of sentence on a pending felony
charge, and if an indeterminate sentence of imprisonment is  imposed  in
each  case,  such  sentences shall run consecutively. Provided, however,
that the court may, in the interest of justice, order a sentence to  run
concurrently  in a situation where consecutive sentences are required by
this subdivision if it finds either mitigating circumstances  that  bear
directly  upon the manner in which the crime was committed or, where the
defendant was not the sole participant in  the  crime,  the  defendant's
participation   was  relatively  minor  although  not  so  minor  as  to
constitute a defense to the prosecution. The defendant and the  district
attorney  shall  have  an opportunity to present relevant information to
assist the court in making this determination and the court may, in  its
discretion,  conduct  a  hearing  with respect to any issue bearing upon
such determination. If the court determines that  consecutive  sentences
should  not  be  ordered, it shall make a statement on the record of the
facts and circumstances upon which such determination is based.
* NB Effective 2005/09/30
  2-c.  When  a person is convicted of bail jumping in the second degree
as defined in section 215.56 or bail jumping  in  the  first  degree  as
defined in section 215.57 committed after arraignment and while released
on recognizance or bail in  connection  with  a  pending  indictment  or
information  charging  one or more felonies, at least one of which he is
subsequently convicted, and if an indeterminate sentence of imprisonment
is  imposed  in  each  case,  such  sentences  shall  run consecutively.
Provided, however, that the court may, in the interest of justice, order
a  sentence  to  run  concurrently  in  a  situation  where  consecutive
sentences are required  by  this  subdivision  if  it  finds  mitigating
circumstances  that bear directly upon the manner in which the crime was
committed. The  defendant  and  the  district  attorney  shall  have  an
opportunity  to  present  relevant  information  to  assist the court in
making this determination and the court may, in its discretion,  conduct
a  hearing with respect to any issue bearing upon such determination. If
the court determines that consecutive sentences should not  be  ordered,
it  shall  make a statement on the record of the facts and circumstances
upon which such determination is based.
   2-d.  When  a  person  is convicted of escape in the second degree as
defined in section 205.10 or escape in the first degree  as  defined  in
section  205.15 committed after issuance of a securing order, as defined
in subdivision five of section 500.10 of the criminal procedure law,  in
connection with a pending indictment or information charging one or more
felonies, at least one of which he is subsequently convicted, and if  an
indeterminate  sentence  of  imprisonment  is imposed in each case, such
sentences shall run consecutively. Provided,  however,  that  the  court
may, in the interest of justice, order a sentence to run concurrently in
a situation where consecutive sentences are required by this subdivision
if  it finds mitigating circumstances that bear directly upon the manner
in which the  crime  was  committed.  The  defendant  and  the  district
attorney  shall  have  an opportunity to present relevant information to
assist the court in making this determination and the court may, in  its
discretion,  conduct  a  hearing  with respect to any issue bearing upon
such determination. If the court determines that  consecutive  sentences
should  not  be  ordered, it shall make a statement on the record of the
facts and circumstances upon which such determination is based.

in section 130.80 and any other crime under article one  hundred  thirty
committed  against  the  same  child and within the period charged under
section 130.75 or 130.80, the sentences must run concurrently.

  2-f. Whenever a person is convicted of facilitating a sex offense with
a controlled substance as defined in section 130.90 of this chapter, the
sentence imposed by the court for such offense may  be  ordered  to  run
consecutively  to  any  sentence  imposed  upon conviction of an offense
defined in article one hundred thirty of this chapter arising  from  the
same criminal transaction.
Effective 2/1/01.

prohibited by subdivision two of this  section  and  are  imposed  on  a
person  for  offenses which were committed as parts of a single incident
or transaction, the aggregate of the terms of such sentences  shall  not
exceed one year.

imprisonment by a court of this state, the sentence or sentences imposed
by  the  court  of this state, subject to the provisions of subdivisions
one, two and three of this section, shall  run  either  concurrently  or
consecutively  with  respect to such undischarged term in such manner as
the court directs at the time of sentence. If the court  of  this  state
